History

Believed to be the source for the Cambodian god Preas Prohm, this god once had his beard turned red by the powerful weapon of Jalamdhara and gave qualified immortality to Taraka. He was charmed by an arrow into screwing his daughter immediately after the birth of Kama. The temple at Pushkar is one of the few dedicated to this god, who sprouted a new head to look at Satarupa every time she moved. Born with a thousand thighs, heads, arms, and eyes as the being Purusha, he is attended by the swan Hamsa, and his wife is the goddess of learning Sarasvati. His masculine name is similar to the neuter word for the principle underlying the universe, as well as to the name of the highest caste. FTP, name this often four-headed and four-handed creator-god of Hinduism.
