According to the ancient Mythology goddess
Kadru is the daughter of Daksha and the wife of Kashyapa. By the
Adi Parva in
Mahabharata Kadru is measured to be the mother of the Nagas. The most important
thing about goddess Kadru is her being a mother of "a thousand powerful
many-headed serpents, the leader amongst who were Sesha, Vasuki and various
violent and poisonous serpents." Once a time, goddess Kadru (the ancestral
mother of snakes) made a bet with her sister Vinata, the bet stands for that
loser would be imprisoned to the winner. Goddess Kadru appeal for the
collaboration of her children in order to fix the bet so that Kadru would win.
When her children balked the appeal, Kadru grow angrier and cursed them to die a
scorching death in the snake-sacrifice of King Janamejaya, who is the son of
king Parikshit, the son of Abhimanyu the son of Arjuna. The king of snakes
Vasuki was responsive of irritation, and well knew that his brethren would want
a hero to free them from it. He moves toward the famous frugal Jaratkaru with a
proposal of marriage to a snake-goddess, Manasa, Vasuki's own sister.
