The Dvaita Vedanta philosophical tradition, established by the philosopher Madhva (1197–1276), has three kinds of beings. Tamoyoga is one of them.
Madhva's core belief was that God was completely
transcendent, being above and beyond the earth and human people.
Because human beings are incapable of saving themselves, he
stressed the necessity of grace as the only way of redemption.
Madhva categorized the world's creatures into three groups
based on their human capacities: the muktiyogas were predestined for ultimate
liberation, the nityasam sarins were doomed for everlasting reincarnation, and
the tamoyogas were predestined for perpetual damnation.
