During this peaceful time, Kroni was born. Kroni, who is analogous to Satan in the Christian tradition, is viewed as a primordial personification of evil. Though Kroni is said to have been born with multitudinous limbs, each the size of a mountain, he nevertheless assumes different forms in different yukams: for example, as Ravana or Duroyodhana. In opposition, Vishnu also incarnates in different yukam with different Avatars, for example Rama or Krishna.
