A famous Indian Buddhist master of the fifth century who clarified the implicit meaning of Buddha’s Perfection of Wisdom Sutras, and the principal exponder of the Mind Only (Skt. Chittamatra) teachings. He had a very close connection to Buddha Maitreya. Due to his great compassion, he was famously able to purify all his karmic obstructions so that he could see his Spiritual Guide, Buddha Maitreya, directly.
