2) Colour of the horse. Once, during a controversy, Vinatā, wife of Kaśyapa, contended that the colour of Uccaiśravas was white, while another wife of Kaśyapa, Kadrū said that its tail was black in colour. It was decided to bet that she who got defeated in this controversy should become the slave of the winner. Because the serpents, the sons of Kadrū, cheated Vinatā, she had to become Kadrū's slave. (See under Vinatā). (M.B. Ādi Parva, Chapter 20).
