Vasuki is the king of the nagas in Hinduism. He is described as having a gem called Nāgamani on his head. Shesha, another king of the nagas and the bed on which Vishnu rests, is his elder brother, and Manasa, another naga, is his sister. In Hindu iconography, he is generally depicted coiling around the neck of Shiva, who is believed to have blessed and worn him as an ornament.
