the puranas are scriptures that tell the birth of manasa. the story states that sage kashyapa was the father not shiva. the story narrates that the serpents and reptiles created chaos on the earth. the sage kashyapa created manas out of his mind (mana). the creator god brahma made manasa a deity of snakes and poison. mansa then gained control over the earth by chanting mantras (prayers). manasa then pleased shiva, who told her to please krishna. because krishna was pleased he granted her divine siddhi powers and made her an official goddess by worshiping her ritually.
