(Var Asa, M. l, p. 470) Comments : In Treta Yuga, the Dharma-Bull stood only on three legs. One-fourth of his merit was lost. The malice grew up in the minds of the people. They became shrewd and began to act with motives. Still they were devoted to their duties and performed the rites and ceremonies punctually. See : Yugas.
