Chih-tun (314-66). A monk of south China during the Eastern Chin dynasty. He was primarily a student of Perfection of Insight (prajñā-pāramitā) literature, but interacted with the Neo- Taoist movement all his life. He used Buddhist ideas to correct what he perceived as mistakes in the Taoist view of the world, and was famous for writing a commentary on a chapter in the Taoist classic Chuang-tzu. In it, he argued that people were not prisoners of their own destiny, and that happiness was thus not to be found in simply following one's own inclinations, but in perfecting oneself through active cultivation. He is also said to have made an image of the Buddha Amitābha and to have vowed to seek rebirth in his Pure Land, but he had no discernible impact on the development of Pure Land Buddhism in China.
