Manasa (Sanskrit: मनसा, romanized: Manasā) is a Hindu goddess of snakes. She is worshipped mainly in Bihar, Bengal, Jharkhand, Lower 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 Hindu mythology, Manasa is the sister of the first two naga kings, Shesha and Vasuki, and the wife of Sage Jaratkaru. She is the mother of the sage Astika. She is also known as Vishahari (the destroyer of poison), Nityā (eternal) and Padmavati. In the Puranas, the sage Kashyapa is considered to be her father, one legend stating that she was created from his mind, and the other stating that she is his daughter from his wife, Kadru. In regional tradition, her myths emphasise her bad temper and unhappiness, due to rejection by her father, Shiva, and her husband, and the hate of her stepmother Chandi (Shiva's wife, identified with Parvati in this context). Manasa is depicted as kind to her devotees, but harsh toward people who refuse to worship her. Denied full godhead due to her mixed parentage, Manasa's aim was to fully establish her authority as a goddess, and to acquire steadfast human devotees. From Wikipedia
