Manasamangal Kāvya ( Bengali: মনসামঙ্গল কাব্য ) is the oldest of the Mangal-Kāvya and narrates how the snake-goddess Manasa established her worship in Bengal by converting a worshipper of Shiva to her own worship. Manasa was a non-Aryan deity and her worship was an ancient one in Bengal. It is believed she came to Bengal with the Dravidians who worshipped her in the hope that she would protect them against snakes. Manasa is also known as Bisahari, Janguli and Padmavati.
