Borobudur

Straight-line arrangement of Borobudur, Pawon, and Mendut

Approximately 40 kilometres (25 mi) northwest of Yogyakarta and 86 kilometres (53 mi) west of Surakarta, Borobudur is located in an elevated area between two twin volcanoes, Sundoro-Sumbing and Merbabu-Merapi, and two rivers, the Progo and the Elo.[20] According to local myth, the area known as Kedu Plain is a Javanese "sacred" place and has been dubbed "the garden of Java" due to its high agricultural fertility.[21]

During the restoration in the early 20th century, it was discovered that three Buddhist temples in the region, Borobudur, Pawon and Mendut, are positioned along a straight line.[22] A ritual relationship between the three temples must have existed, although the exact ritual process is unknown.[15]

Speculation about a surrounding lake's existence was the subject of intense discussion among archaeologists in the 20th century. In 1931, a Dutch artist and scholar of Hindu and Buddhist architecture, W.O.J. Nieuwenkamp, developed a hypothesis that the Kedu Plain was once a lake and Borobudur initially represented a lotus flower floating on the lake.[16] It has been claimed that Borobudur was built on a bedrock hill, 265 m (869 ft) above sea level and 15 m (49 ft) above the floor of a dried-out paleolake.[23]

Dumarçay together with Professor Thanikaimoni took soil samples in 1974 and again in 1977 from trial trenches that had been dug into the hill, as well as from the plain immediately to the south. These samples were later analysed by Thanikaimoni, who examined their pollen and spore content to identify the type of vegetation that had grown in the area around the time of Borobudur's construction. They were unable to discover any pollen or spore samples that were characteristic of any vegetation known to grow in an aquatic environment such as a lake, pond or marsh. The area surrounding Borobudur appears to have been surrounded by agricultural land and palm trees at the time of the monument's construction, as is still the case today. Caesar Voûte and the geomorphologist Dr J.J. Nossin in 1985–86 field studies re-examined the Borobudur lake hypothesis and confirmed the absence of a lake around Borobudur at the time of its construction and active use as a sanctuary. These findings A New Perspective on Some Old Questions Pertaining to Borobudur were published in the 2005 UNESCO publication titled "The Restoration of Borobudur".

There are no known records of construction or the intended purpose of Borobudur.[24] The duration of construction has been estimated by comparison of carved reliefs on the temple's hidden foot and the inscriptions commonly used in royal charters during the 8th and 9th centuries. Borobudur was likely founded around 800 AD.[24] This corresponds to the period between 760 and 830 AD, the peak of the Sailendra dynasty rule over Mataram kingdom in central Java,[25] when their power encompassed not only the Srivijayan Empire but also southern Thailand, Indianized kingdoms of Philippines, North Malaya (Kedah, also known in Indian texts as the ancient Hindu state of Kadaram).[26][27][28] The construction has been estimated to have taken 75 years with completion during the reign of Samaratungga in 825.[29][30]

There is uncertainty about Hindu and Buddhist rulers in Java around that time. The Sailendras were known as ardent followers of Buddhism, though stone inscriptions found at Sojomerto also suggest they may have been Hindus.[29] It was during this time that many Hindu and Buddhist monuments were built on the plains and mountains around the Kedu Plain. The Buddhist monuments, including Borobudur, were erected around the same period as the Hindu Shiva Prambanan temple compound. In 732 AD, the Shivaite King Sanjaya commissioned a Shivalinga sanctuary to be built on the Wukir hill, only 10 km (6.2 mi) east of Borobudur.[31]

Construction of Buddhist temples, including Borobudur, at that time was possible because Sanjaya's immediate successor, Rakai Panangkaran, granted his permission to the Buddhist followers to build such temples.[32] In fact, to show his respect, Panangkaran gave the village of Kalasan to the Buddhist community, as is written in the Kalasan Charter dated 778 AD.[32] This has led some archaeologists to believe that there was never serious conflict concerning religion in Java as it was possible for a Hindu king to patronize the establishment of a Buddhist monument; or for a Buddhist king to act likewise.[33] However, it is likely that there were two rival royal dynasties in Java at the time—the Buddhist Sailendra and the Saivite Sanjaya—in which the latter triumphed over their rival in the 856 battle on the Ratubaka plateau.[34] Similar confusion also exists regarding the Lara Jonggrang temple at the Prambanan complex, which was believed to have been erected by the victor Rakai Pikatan as the Sanjaya dynasty's reply to Borobudur,[34] but others suggest that there was a climate of peaceful coexistence where Sailendra involvement exists in Lara Jonggrang.[35]

Borobudur lay hidden for centuries under layers of volcanic ash and jungle growth. The facts behind its abandonment remain a mystery. It is not known when active use of the monument and Buddhist pilgrimage to it ceased. Sometime between 928 and 1006, King Mpu Sindok moved the capital of the Medang Kingdom to the region of East Java after a series of volcanic eruptions; it is not certain whether this influenced the abandonment, but several sources mention this as the most likely period of abandonment.[8][23] The monument is mentioned vaguely as late as c. 1365, in Mpu Prapanca's Nagarakretagama, written during the Majapahit era and mentioning "the vihara in Budur".[36] Soekmono (1976) also mentions the popular belief that the temples were disbanded when the population converted to Islam in the 15th century.[8]

The monument was not forgotten completely, though folk stories gradually shifted from its past glory into more superstitious beliefs associated with bad luck and misery. Two old Javanese chronicles (babad) from the 18th century mention cases of bad luck associated with the monument. According to the Babad Tanah Jawi (or the History of Java), the monument was a fatal factor for Mas Dana, a rebel who revolted against Pakubuwono I, the king of Mataram in 1709.[8] It was mentioned that the "Redi Borobudur" hill was besieged and the insurgents were defeated and sentenced to death by the king. In the Babad Mataram (or the History of the Mataram Kingdom), the monument was associated with the misfortune of Prince Monconagoro, the crown prince of the Yogyakarta Sultanate in 1757.[37] In spite of a taboo against visiting the monument, "he took what is written as the knight who was captured in a cage (a statue in one of the perforated stupas)". Upon returning to his palace, he fell ill and died one day later.

Borobudur's main stupa in mid 19th-century, a wooden deck had been installed above the main stupa.

Following its capture, Java was under British administration from 1811 to 1816. The appointed governor was Lieutenant Governor-General Thomas Stamford Raffles, who took great interest in the history of Java. He collected Javanese antiques and made notes through contacts with local inhabitants during his tour throughout the island. On an inspection tour to Semarang in 1814, he was informed about a big monument deep in a jungle near the village of Bumisegoro.[37] He was not able to see the site himself, but sent Hermann Cornelius, a Dutch engineer who, among other antiquity explorations had uncovered the Sewu complex in 1806–07, to investigate. In two months, Cornelius and his 200 men cut down trees, burned down vegetation and dug away the earth to reveal the monument. Due to the danger of collapse, he could not unearth all galleries. He reported his findings to Raffles, including various drawings. Although Raffles mentioned the discovery and hard work by Cornelius and his men in only a few sentences, he has been credited with the monument's rediscovery, as the one who had brought it to the world's attention.[14]

Christiaan Lodewijk Hartmann, the Resident of the Kedu region, continued Cornelius's work, and in 1835, the whole complex was finally unearthed. His interest in Borobudur was more personal than official. Hartmann did not write any reports of his activities, in particular, the alleged story that he discovered the large statue of Buddha in the main stupa.[38] In 1842, Hartmann investigated the main dome, although what he discovered is unknown and the main stupa remains empty.

Borobudur in 1872.

The Dutch East Indies government then commissioned Frans Carel Wilsen, a Dutch engineering official, who studied the monument and drew hundreds of relief sketches. Jan Frederik Gerrit Brumund was also appointed to make a detailed study of the monument, which was completed in 1859. The government intended to publish an article based on Brumund's study supplemented by Wilsen's drawings, but Brumund refused to cooperate. The government then commissioned another scholar, Conradus Leemans, who compiled a monograph based on Brumund's and Wilsen's sources. In 1873, the first monograph of the detailed study of Borobudur was published, followed by its French translation a year later.[38] The first photograph of the monument was taken in 1872 by the Dutch-Flemish engraver Isidore van Kinsbergen.[39]

Appreciation of the site developed slowly, and it served for some time largely as a source of souvenirs and income for "souvenir hunters" and thieves. In 1882, the chief inspector of cultural artifacts recommended that Borobudur be entirely disassembled with the relocation of reliefs into museums due to the unstable condition of the monument.[39] As a result, the government appointed Willem Pieter Groeneveldt, curator of the archaeological collection of the Batavian Society of Arts and Sciences,[40] to undertake a thorough investigation of the site and to assess the actual condition of the complex; his report found that these fears were unjustified and recommended it be left intact.

Borobudur was considered as the source of souvenirs, and parts of its sculptures were looted, some even with colonial-government consent. In 1896 King Chulalongkorn of Siam visited Java and requested and was allowed to take home eight cartloads of sculptures taken from Borobudur. These include thirty pieces taken from a number of relief panels, five buddha images, two lions, one gargoyle, several kala motifs from the stairs and gateways, and a guardian statue (dvarapala). Several of these artifacts, most notably the lions, dvarapala, kala, makara and giant waterspouts are now on display in the Java Art room in The National Museum in Bangkok.[41]

Borobudur attracted attention in 1885, when the Dutch engineer Jan Willem IJzerman, Chairman of the Archaeological Society in Yogyakarta, made a discovery about the hidden foot.[42] Photographs that reveal reliefs on the hidden foot were made in 1890–1891.[43] The discovery led the Dutch East Indies government to take steps to safeguard the monument. In 1900, the government set up a commission consisting of three officials to assess the monument: Jan Lourens Andries Brandes, an art historian, Theodoor van Erp, a Dutch army engineer officer, and Benjamin Willem van de Kamer, a construction engineer from the Department of Public Works.

In 1902, the commission submitted a threefold plan of proposal to the government. First, the immediate dangers should be avoided by resetting the corners, removing stones that endangered the adjacent parts, strengthening the first balustrades and restoring several niches, archways, stupas and the main dome. Second, after fencing off the courtyards, proper maintenance should be provided and drainage should be improved by restoring floors and spouts. Third, all loose stones should be removed, the monument cleared up to the first balustrades, disfigured stones removed and the main dome restored. The total cost was estimated at that time around 48,800 Dutch guilders.

The restoration then was carried out between 1907 and 1911, using the principles of anastylosis and led by Theodor van Erp.[44] The first seven months of restoration were occupied with excavating the grounds around the monument to find missing Buddha heads and panel stones. Van Erp dismantled and rebuilt the upper three circular platforms and stupas. Along the way, Van Erp discovered more things he could do to improve the monument; he submitted another proposal, which was approved with the additional cost of 34,600 guilders. At first glance, Borobudur had been restored to its old glory. Van Erp went further by carefully reconstructing the chattra (three-tiered parasol) pinnacle on top of the main stupa. However, he later dismantled the chattra, citing that there were not enough original stones used in reconstructing the pinnacle, which means that the original design of Borobudur's pinnacle is actually unknown. The dismantled chattra now is stored in Karmawibhangga Museum, a few hundred meters north from Borobudur.

Due to the limited budget, the restoration had been primarily focused on cleaning the sculptures, and Van Erp did not solve the drainage problem. Within fifteen years, the gallery walls were sagging, and the reliefs showed signs of new cracks and deterioration.[44] Van Erp used concrete from which alkali salts and calcium hydroxide leached and were transported into the rest of the construction. This caused some problems, so that a further thorough renovation was urgently needed.

Small restorations had been performed since then, but not sufficient for complete protection. During World War II and Indonesian National Revolution in 1945 to 1949, Borobudur restoration efforts were halted. The monument suffered further from the weather and drainage problems, which caused the earth core inside the temple to expand, pushing the stone structure and tilting the walls. By 1950s some parts of Borobudur were facing imminent danger of collapsing. In 1965, Indonesia asked the UNESCO for advice on ways to counteract the problem of weathering at Borobudur and other monuments. In 1968 Professor Soekmono, then head of the Archeological Service of Indonesia, launched his "Save Borobudur" campaign, in an effort to organize a massive restoration project.[45]

In the late 1960s, the Indonesian government had requested from the international community a major renovation to protect the monument. In 1973, a master plan to restore Borobudur was created.[46] Through an Agreement concerning the Voluntary Contributions to be Given for the Execution of the Project to Preserve Borobudur (Paris, 29 January 1973), 5 countries agreed to contribute to the restoration: Australia (AUD $200,000), Belgium (BEF fr.250,000), Cyprus (CYP £100,000), France (USD $77,500) and Germany (DEM DM 2,000,000).[47] The Indonesian government and UNESCO then undertook the complete overhaul of the monument in a big restoration project between 1975 and 1982.[44] In 1975, the actual work began. Over one million stones were dismantled and removed during the restoration, and set aside like pieces of a massive jig-saw puzzle to be individually identified, catalogued, cleaned and treated for preservation. Borobudur became a testing ground for new conservation techniques, including new procedures to battle the microorganisms attacking the stone.[45] The foundation was stabilized, and all 1,460 panels were cleaned. The restoration involved the dismantling of the five square platforms and the improvement of drainage by embedding water channels into the monument. Both impermeable and filter layers were added. This colossal project involved around 600 people to restore the monument and cost a total of US$6,901,243.[48]

After the renovation was finished, UNESCO listed Borobudur as a World Heritage Site in 1991.[3] It is listed under Cultural criteria (i) "to represent a masterpiece of human creative genius", (ii) "to exhibit an important interchange of human values, over a span of time or within a cultural area of the world, on developments in architecture or technology, monumental arts, town-planning or landscape design", and (vi) "to be directly or tangibly associated with events or living traditions, with ideas, or with beliefs, with artistic and literary works of outstanding universal significance".[3]

In December 2017, the idea to reinstall chattra on top of Borobudur main stupa's yasthi has been revisited. However, expert said a thorough study is needed on restoring the umbrella-shaped pinnacle. By early 2018, the chattra restoration has not yet commenced.[49]

Following the major 1973 renovation funded by UNESCO,[46] Borobudur is once again used as a place of worship and pilgrimage. Once a year, during the full moon in May or June, Buddhists in Indonesia observe Vesak (Indonesian: Waisak) day commemorating the birth, death, and the time when Siddhārtha Gautama attained the highest wisdom to become the Buddha Shakyamuni. Vesak is an official national holiday in Indonesia,[50] and the ceremony is centered at the three Buddhist temples by walking from Mendut to Pawon and ending at Borobudur.[51]

The monument is the single most visited tourist attraction in Indonesia. In 1974, 260,000 tourists, of whom 36,000 were foreigners, visited the monument.[11] The figure climbed to 2.5 million visitors annually (80% were domestic tourists) in the mid-1990s, before the country's economic crisis.[12] Tourism development, however, has been criticized for not including the local community, giving rise to occasional conflicts.[11] In 2003, residents and small businesses around Borobudur organized several meetings and poetry protests, objecting to a provincial government plan to build a three-storey mall complex, dubbed the "Java World".[52]

International tourism awards were given to Borobudur archaeological park, such as PATA Grand Pacific Award 2004, PATA Gold Award Winner 2011, and PATA Gold Award Winner 2012. In June 2012, Borobudur was recorded in the Guinness Book of World Records as the world's largest Buddhist archaeological site.[53]

UNESCO identified three specific areas of concern under the present state of conservation: (i) vandalism by visitors; (ii) soil erosion in the south-eastern part of the site; and (iii) analysis and restoration of missing elements.[54] The soft soil, the numerous earthquakes and heavy rains lead to the destabilization of the structure. Earthquakes are by far the most important contributing factors, since not only do stones fall down and arches crumble, but the earth itself can move in waves, further destroying the structure.[54] The increasing popularity of the stupa brings in many visitors, most of whom are from Indonesia. Despite warning signs on all levels not to touch anything, the regular transmission of warnings over loudspeakers and the presence of guards, vandalism on reliefs and statues is a common occurrence and problem, leading to further deterioration. As of 2009, there is no system in place to limit the number of visitors allowed per day or to introduce mandatory guided tours only.[54]

In August 2014, the Conservation Authority of Borobudur reported some severe abrasion of the stone stairs caused by the scraping of visitors' footwear. The conservation authority planned to install wooden stairs to cover and protect the original stone stairs, just like those installed in Angkor Wat.[55]

Location of Borobudur relative to Mount Merapi and Yogyakarta

Borobudur was heavily affected by the eruption of Mount Merapi in October and November 2010. Volcanic ash from Merapi fell on the temple complex, which is approximately 28 kilometres (17 mi) west-southwest of the crater. A layer of ash up to 2.5 centimetres (1 in)[56] thick fell on the temple statues during the eruption of 3–5 November, also killing nearby vegetation, with experts fearing that the acidic ash might damage the historic site. The temple complex was closed from 5 to 9 November to clean up the ashfall.[57][58]

UNESCO donated US$3 million as a part of the costs towards the rehabilitation of Borobudur after Mount Merapi's 2010 eruption.[59] More than 55,000 stone blocks comprising the temple's structure were dismantled to restore the drainage system, which had been clogged by slurry after the rain. The restoration was finished in November.[60]

Borobudur is surrounded by mountains, including twin volcanoes; Mount Merbabu and Merapi

In January 2012, two German stone-conservation experts spent ten days at the site analyzing the temples and making recommendations to ensure their long-term preservation.[61] In June, Germany agreed to contribute $130,000 to UNESCO for the second phase of rehabilitation, in which six experts in stone conservation, microbiology, structural engineering and chemical engineering would spend a week in Borobudur in June, then return for another visit in September or October. These missions would launch the preservation activities recommended in the January report and would include capacity building activities to enhance the preservation capabilities of governmental staff and young conservation experts.[62]

On 14 February 2014, major tourist attractions in Yogyakarta and Central Java, including Borobudur, Prambanan and Ratu Boko, were closed to visitors, after being severely affected by the volcanic ash from the eruption of Kelud volcano in East Java, located around 200 kilometers east from Yogyakarta. Workers covered the iconic stupas and statues of Borobudur temple to protect the structure from volcanic ash. The Kelud volcano erupted on 13 February 2014 with an explosion heard as far away as Yogyakarta.[63]

On 21 January 1985, nine stupas were badly damaged by nine bombs.[64][65] In 1991, a blind Muslim preacher, Husein Ali Al Habsyie, was sentenced to life imprisonment for masterminding a series of bombings in the mid-1980s, including the temple attack.[66] Two other members of the Islamic extremist group that carried out the bombings were each sentenced to 20 years in 1986, and another man received a 13-year prison term.

On 27 May 2006, an earthquake of 6.2 magnitude struck the south coast of Central Java. The event caused severe damage around the region and casualties to the nearby city of Yogyakarta, but Borobudur remained intact.[67]

In August 2014, Indonesian police and security forces tightened the security in and around Borobudur temple compound, as a precaution to a threat posted on social media by a self-proclaimed Indonesian branch of ISIS, citing that the terrorists planned to destroy Borobudur and other statues in Indonesia.[68] The security improvements included the repair and increased deployment of CCTV monitors and the implementation of a night patrol in and around the temple compound. The jihadist group follows a strict interpretation of Islam that condemns any anthropomorphic representations such as sculptures as idolatry.

Tourists in Borobudur

The high volume of visitors ascending the Borobudur's narrow stairs, has caused a severe wear out on the stone of the stairs, eroding the stones surface and made them thinner and smoother. Overall, Borobudur has 2,033 surfaces of stone stairs, spread over four cardinal directions; including the west side, the east, south and north. There are around 1,028 surfaces of them, or about 49.15 percent, that are severely worn out.[69]

To avoid further wear of stairs' stones, since November 2014, two main sections of Borobudur stairs – the eastern (ascending route) and northern (descending route) sides – are covered with wooden structures. The similar technique has been applied in Angkor Wat in Cambodia and Egyptian Pyramids.[69] In March 2015, Borobudur Conservation Center proposed further to seal the stairs with rubber cover.[70] Proposals have also been made that visitors be issued special sandals.[71]

Borobudur ground plan taking the form of a Mandala

Borobudur is built as a single large stupa and, when viewed from above, takes the form of a giant tantric Buddhist mandala, simultaneously representing the Buddhist cosmology and the nature of mind.[73] The original foundation is a square, approximately 118 metres (387 ft) on each side. It has nine platforms, of which the lower six are square and the upper three are circular.[74] The upper platform contains seventy-two small stupas surrounding one large central stupa. Each stupa is bell-shaped and pierced by numerous decorative openings. Statues of the Buddha sit inside the pierced enclosures.

The design of Borobudur took the form of a step pyramid. Previously, the prehistoric Austronesian megalithic culture in Indonesia had constructed several earth mounds and stone step pyramid structures called punden berundak as discovered in Pangguyangan site near Cisolok[75] and in Cipari near Kuningan.[76] The construction of stone pyramids is based on native beliefs that mountains and high places are the abode of ancestral spirits or hyangs.[77] The punden berundak step pyramid is the basic design in Borobudur,[78] believed to be the continuation of older megalithic tradition incorporated with Mahayana Buddhist ideas and symbolism.[79]

The monument's three divisions symbolize the three "realms" of Buddhist cosmology, namely Kamadhatu (the world of desires), Rupadhatu (the world of forms), and finally Arupadhatu (the formless world). Ordinary sentient beings live out their lives on the lowest level, the realm of desire. Those who have burnt out all desire for continued existence leave the world of desire and live in the world on the level of form alone: they see forms but are not drawn to them. Finally, full Buddhas go beyond even form and experience reality at its purest, most fundamental level, the formless ocean of nirvana.[80] The liberation from the cycle of Saṃsāra where the enlightened soul had no longer attached to worldly form corresponds to the concept of Śūnyatā, the complete voidness or the nonexistence of the self. Kāmadhātu is represented by the base, Rupadhatu by the five square platforms (the body), and Arupadhatu by the three circular platforms and the large topmost stupa. The architectural features between the three stages have metaphorical differences. For instance, square and detailed decorations in the Rupadhatu disappear into plain circular platforms in the Arupadhatu to represent how the world of forms—where men are still attached with forms and names—changes into the world of the formless.[81]

Congregational worship in Borobudur is performed in a walking pilgrimage. Pilgrims are guided by the system of staircases and corridors ascending to the top platform. Each platform represents one stage of enlightenment. The path that guides pilgrims was designed to symbolize Buddhist cosmology.[82]

In 1885, a hidden structure under the base was accidentally discovered.[42] The "hidden footing" contains reliefs, 160 of which are narratives describing the real Kāmadhātu. The remaining reliefs are panels with short inscriptions that apparently provide instructions for the sculptors, illustrating the scenes to be carved.[83] The real base is hidden by an encasement base, the purpose of which remains a mystery. It was first thought that the real base had to be covered to prevent a disastrous subsidence of the monument into the hill.[83] There is another theory that the encasement base was added because the original hidden footing was incorrectly designed, according to Vastu Shastra, the Indian ancient book about architecture and town planning.[42] Regardless of why it was commissioned, the encasement base was built with detailed and meticulous design and with aesthetic and religious consideration.

Half cross-section with 4:6:9 height ratio for foot, body and head, respectively

Approximately 55,000 cubic metres (72,000 cu yd) of andesite stones were taken from neighbouring stone quarries to build the monument.[84] The stone was cut to size, transported to the site and laid without mortar. Knobs, indentations and dovetails were used to form joints between stones. The roof of stupas, niches and arched gateways were constructed in corbelling method. Reliefs were created in situ after the building had been completed.

The monument is equipped with a good drainage system to cater to the area's high stormwater run-off. To prevent flooding, 100 spouts are installed at each corner, each with a unique carved gargoyle in the shape of a giant or makara.

Borobudur differs markedly from the general design of other structures built for this purpose. Instead of being built on a flat surface, Borobudur is built on a natural hill. However, construction technique is similar to other temples in Java. Without the inner spaces seen in other temples, and with a general design similar to the shape of pyramid, Borobudur was first thought more likely to have served as a stupa, instead of a temple.[84] A stupa is intended as a shrine for the Buddha. Sometimes stupas were built only as devotional symbols of Buddhism. A temple, on the other hand, is used as a house of worship. The meticulous complexity of the monument's design suggests that Borobudur is in fact a temple.

Little is known about Gunadharma, the architect of the complex.[85] His name is recounted from Javanese folk tales rather than from written inscriptions.

The basic unit of measurement used during construction was the tala, defined as the length of a human face from the forehead's hairline to the tip of the chin or the distance from the tip of the thumb to the tip of the middle finger when both fingers are stretched at their maximum distance.[86] The unit is thus relative from one individual to the next, but the monument has exact measurements. A survey conducted in 1977 revealed frequent findings of a ratio of 4:6:9 around the monument. The architect had used the formula to lay out the precise dimensions of the fractal and self-similar geometry in Borobudur's design.[86][87] This ratio is also found in the designs of Pawon and Mendut, nearby Buddhist temples. Archeologists have conjectured that the 4:6:9 ratio and the tala have calendrical, astronomical and cosmological significance, as is the case with the temple of Angkor Wat in Cambodia.[85]

The main structure can be divided into three components: base, body, and top.[85] The base is 123 m × 123 m (404 ft × 404 ft) in size with 4 metres (13 ft) walls.[84] The body is composed of five square platforms, each of diminishing height. The first terrace is set back 7 metres (23 ft) from the edge of the base. Each subsequent terrace is set back 2 metres (6.6 ft), leaving a narrow corridor at each stage. The top consists of three circular platforms, with each stage supporting a row of perforated stupas, arranged in concentric circles. There is one main dome at the center, the top of which is the highest point of the monument, 35 metres (115 ft) above ground level. Stairways at the center of each of the four sides give access to the top, with a number of arched gates overlooked by 32 lion statues. The gates are adorned with Kala's head carved on top of each and Makaras projecting from each side. This Kala-Makara motif is commonly found on the gates of Javanese temples. The main entrance is on the eastern side, the location of the first narrative reliefs. Stairways on the slopes of the hill also link the monument to the low-lying plain.

The 160 hidden panels do not form a continuous story, but each panel provides one complete illustration of cause and effect.[94] There are depictions of blameworthy activities, from gossip to murder, with their corresponding punishments. There are also praiseworthy activities, that include charity and pilgrimage to sanctuaries, and their subsequent rewards. The pains of hell and the pleasure of heaven are also illustrated. There are scenes of daily life, complete with the full panorama of samsara (the endless cycle of birth and death). The encasement base of the Borobudur temple was disassembled to reveal the hidden foot, and the reliefs were photographed by Casijan Chepas in 1890. It is these photographs that are displayed in Borobudur Museum (Karmawibhangga Museum), located just several hundred meters north of the temple. During the restoration, the foot encasement was reinstalled, covering the Karmawibhangga reliefs. Today, only the southeast corner of the hidden foot is revealed and visible for visitors.

Queen Maya riding horse carriage retreating to Lumbini to give birth to Prince Siddhartha Gautama

The story starts with the descent of the Buddha from the Tushita heaven and ends with his first sermon in the Deer Park near Benares.[96] The relief shows the birth of the Buddha as Prince Siddhartha, son of King Suddhodana and Queen Maya of Kapilavastu (in Nepal).

The story is preceded by 27 panels showing various preparations, in the heavens and on the earth, to welcome the final incarnation of the Bodhisattva.[96] Before descending from Tushita heaven, the Bodhisattva entrusted his crown to his successor, the future Buddha Maitreya. He descended on earth in the shape of white elephants with six tusks, penetrated to Queen Maya's right womb. Queen Maya had a dream of this event, which was interpreted that his son would become either a sovereign or a Buddha.

Prince Siddhartha Gautama became an ascetic hermit.

While Queen Maya felt that it was the time to give birth, she went to the Lumbini park outside the Kapilavastu city. She stood under a plaksa tree, holding one branch with her right hand, and she gave birth to a son, Prince Siddhartha. The story on the panels continues until the prince becomes the Buddha.

Jatakas are stories about the Buddha before he was born as Prince Siddhartha.[97] They are the stories that tell about the previous lives of the Buddha, in both human and animal form. The future Buddha may appear in them as a king, an outcast, a god, an elephant—but, in whatever form, he exhibits some virtue that the tale thereby inculcates.[98] Avadanas are similar to jatakas, but the main figure is not the Bodhisattva himself. The saintly deeds in avadanas are attributed to other legendary persons. Jatakas and avadanas are treated in one and the same series in the reliefs of Borobudur.

The first twenty lower panels in the first gallery on the wall depict the Sudhanakumaravadana, or the saintly deeds of Sudhana. The first 135 upper panels in the same gallery on the balustrades are devoted to the 34 legends of the Jatakamala.[99] The remaining 237 panels depict stories from other sources, as do the lower series and panels in the second gallery. Some jatakas are depicted twice, for example the story of King Sibhi (Rama's forefather).

Gandavyuha is the story told in the final chapter of the Avatamsaka Sutra about Sudhana's tireless wandering in search of the Highest Perfect Wisdom. It covers two galleries (third and fourth) and also half of the second gallery, comprising in total of 460 panels.[100] The principal figure of the story, the youth Sudhana, son of an extremely rich merchant, appears on the 16th panel. The preceding 15 panels form a prologue to the story of the miracles during Buddha's samadhi in the Garden of Jeta at Sravasti.

During his search, Sudhana visited no fewer than thirty teachers, but none of them had satisfied him completely. He was then instructed by Manjusri to meet the monk Megasri, where he was given the first doctrine. As his journey continues, Sudhana meets (in the following order) Supratisthita, the physician Megha (Spirit of Knowledge), the banker Muktaka, the monk Saradhvaja, the upasika Asa (Spirit of Supreme Enlightenment), Bhismottaranirghosa, the Brahmin Jayosmayatna, Princess Maitrayani, the monk Sudarsana, a boy called Indriyesvara, the upasika Prabhuta, the banker Ratnachuda, King Anala, the god Siva Mahadeva, Queen Maya, Bodhisattva Maitreya and then back to Manjusri. Each meeting has given Sudhana a specific doctrine, knowledge and wisdom. These meetings are shown in the third gallery.

After the last meeting with Manjusri, Sudhana went to the residence of Bodhisattva Samantabhadra, depicted in the fourth gallery. The entire series of the fourth gallery is devoted to the teaching of Samantabhadra. The narrative panels finally end with Sudhana's achievement of the Supreme Knowledge and the Ultimate Truth.[101]
