Ravigupta/Suryagupta (Tibetan: nyi ma be pa): from the set of Eighty-four Mahasiddhas according to the text and list of the Indian scholar Vajrasana of Bodhgaya (11th century). Suryagupta was a layperson from Kashmir that was cured of leprosy by a miraculous statue of the goddess Tara. Ravigupta is famous for having many visions of Tara and originating many lineages of her practice such as the Twenty-one forms of Tara, Vajra Tara, Seventeen Deity Tara practice, etc. 

The Twenty-one Deity Tara of Suryagupta is iconographically significantly different from the Twenty-one Taras of Atisha, the Sadhanasamucchaya and others. The Seventeen Deity Tara is unique because the conjoined couple of Tara and Amoghasiddhi present Tara as the central figure.
