In the Hindu epic the Mahabharata,
Ambalika is the daughter of the king of
Kashi and one of the wives of King
Vichitravirya. When Vichitravirya dies
childless, his mother, Satyavati, calls
upon her eldest son, Vyasa, to sleep with
Ambalika and her sister Ambika in the
hope that the women will conceive and
continue the family line. According to
tradition, Vyasa is very ugly, and each
woman involuntarily reacts when Vyasa
appears in her bed. Ambalika turns pale,
causing her son Pandu to be born with
an unnaturally pale complexion, and
Ambika covers her eyes, causing her son
Dhrtarashtra to be born blind.
