Sesha is, in Hindu mythology, the great king of the serpent race, on whom Vishnu reclines on the primeval waters. He has a thousand heads, which serve as a canopy to Vishnu; and he upholds the world, which rests on one of his heads. His crest is ornamented with jewels. Coiled up, Sesha is the emblem of eternity. He is often also called Vasuki or Ananta, "the eternal."
