Āryadeva ［提婆・聖提婆］ (n.d.) (; Daiba or Shōdaiba): Also known as Kānadeva. A scholar of the Mādhyamika school in southern India during the third century and the successor of Nāgārjuna. Born to a Brahman family, he studied the doctrine of non-substantiality under Nāgārjuna. One source regards him as a prince of Sri Lanka. According to The Biography of Bodhisattva Āryadeva, he offered one eye to the god Maheshvara at the latter’s request. Because he had only one eye (the Sanskrit kāna means one-eyed), he was also called Kānadeva. He traveled throughout India to instruct the people. After he defeated non-Buddhist teachers in a religious debate at Pātaliputra, he was killed by one of their disciples. According to the above biography, Āryadeva displayed compassion even during his last moments, telling his assailant about the Buddhist teaching in order to save him. He wrote The One-Hundred-Verse Treatise, The Four-Hundred-Verse Treatise, and The One-Hundred-Word Treatise. The One-Hundred-Verse Treatise is one of the three works on which the Three Treatises (Chin San-lun; Sanron) school was founded. Āryadeva is regarded as the fourteenth of Shakyamuni’s twenty-three, or the fifteenth of his twenty-four, successors. He transferred the Buddha’s teachings he had received from Nāgārjuna to Rāhulabhadra.
