Manasa is a Hindu goddess of snakes. She is worshipped mainly in Bihar, Bengal, Jharkhand, South Assam and other parts of northeastern India and in Uttarakhand, chiefly for the prevention and cure of snakebite, and also for fertility and prosperity. In Hinduism, Manasa is the sister of Shesha and Vasuki, king of Nāgas (serpents), and wife of sage Jaratkaru. She is the mother of the sage Astika. She is also known as Vishahari, Nityā (eternal) and Padmavati.
