An authority on Buddhist philosophy, born in China and educated at Kong-ka Monastery in eastern Tibet, Chang came to the United States after World War II and was a research fellow at the Bollingen Foundation in New York from 1955 onward.
Chang wrote a number of books, including The Practice of Zen (1959), The Hundred Thousand Songs of Milarepa (1962), and The Essential Teachings of the Tibetan Mysticism (1963).
