The fourth patriarch of the Hua-yen school in China. According to legend, he stood over 9 feet tall, his arms extended below his knees, and his eyes glowed in the dark. A member of the monastic order from the age of 11, he travelled extensively around China, studying many Mahāyāna texts with famous masters, concentrating primarily on the Hua-yen ching. In 796, the T'ang emperor invited him to the capital city of Ch'ang-an to assist Prajñā with a new translation of the Sūtra in Forty Fascicles. His own commentaries on the sūtra ran to over 400 fascicles, and he left as his legacy 38 disciples who achieved national prominence. He is credited with extending the influence of the Hua-yen school considerably.
