 Fazang’s ancestors came from Sogdiana (a center for trade along the Silk Road, located in what is now parts of Uzbekistan and Tajikestan), but he was born in the Tang dynasty capital of Chang’an (now Xi’an), where his family had become culturally Chinese. Fazang was a fervently religious adolescent. Following a then-popular custom that took self-immolation as a sign of religious devotion, Fazang burned his fingers before a stupa at the age of 16. After becoming a monk, he assisted Xuanzang—famous for his pilgrimage to India—in translating Buddhist works from Sanskrit into Chinese. Fazang had doctrinal differences with Xuanzang, though, so he later became a disciple of Zhiyan, probably around 663 CE.
