An eleventh-century Kashmiri scholar that was the source from which many prominent Tibetan scholars and translators of the day received teachings. Most notably he taught the Ratnagotravibhāga to Ngok Lotsāwa and Tsen Khawoche, which spread in Tibet as the Ngok and Tsen traditions and became the two primary trends that influenced much of the history of the Tibetan exegesis of the treatise. He also helped Ngok translate the text and worked with several other Tibetan translators on works that were later included in the Tibetan canon.
