Prajñakaramati
Prajñakaramati (Tib. ཤེས་རབ་འབྱུང་གནས་བློ་གྲོས་, sherab jungné lodrö, Wyl. shes rab ‘byung gnas blo gros) (950-1030) was one of the six gate keepers of Vikramashila. Learned in all sciences, he had direct visions of Mañjushri and would invoke him especially when debating with non-Buddhists. This enabled him to give the appropriate answers and to win the discussion. Prajñakaramati is especially renowned in Tibetan Buddhism for what is considered to be the main Indian commentary on Shantideva’s Bodhicharyavatara.
