Tamo-yogyas

In Dvaita philosophy, Tamo-yogyas are a group of souls, classified by His Divine Grace Śrīpāda Madhvācārya, which consists of souls who are the damnable. His Divine Grace divides souls into three classes: one class of souls which qualifies for liberation (Mukti-yogyas), another as subject to eternal rebirth or eternal transmigration (Nitya-samsarins), and a third class that is eventually condemned to eternal hellish life Andhatamisra (Tamo-yogyas).[1][2]

According to Śrīla Madhvācārya, naraka is temporary for sinners like thieves and drunkards, but not for those who express eternal hatred against God, the Dvaita gurus or the Vedas.[3] Therefore, the eternally damned would consist of the most evil, sadomasochistic living entities, including demon Kali who although carries on the orders of the Supreme Personality of Godhead enjoys being punished also, who is said to be the most wicked being.[4] They would sink down into Andhatamisra, which would remain independently during every Kalpa.[5] Some Dvaitins regard this as an expression of universal kindness, because it would fit in with their nature, like the neem tree prefers bitter minerals for its growth.[5]
