Ambika

(2) In one of the great Hindu epics, the
Mahabharata, Ambika is the daughter
of the king of Kashi and the wife of King
Vichitravirya. When Vichitravirya dies
childless, his mother, Satyavati, calls
upon her oldest son, Vyasa, to have sex
with Ambika and her sister Ambalika 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. Ambika covers her
eyes, causing her son Dhrtarashtra to
be born blind, and Ambalika turns pale,
causing her son Pandu to have an
unnaturally pale complexion.
