Sengzhao (or Seng-Chao) (; 僧肇, Sōjō; 384–414)
was a Chinese Buddhist philosopher from Later Qin. Born to a poor family in Jingzhao, he acquired literary skills, apparently including the capacity to read Pali, and became a scribe. This exposed him to a variety of uncommon documents. He was influenced by Taoists, Laozi and Zhuangzi, and although we are told he enjoyed Lao Tzu’s Daodejing (Tao-te ching, Dotokyu-kyo), he was overjoyed when he discovered the Vimalakirti Sutra. This encounter transformed his life and he became a Buddhist. He was known as being among the ablest of the disciples of Kumārajīva.
Sengzhao was recognized as both a scholar of high skill and someone of profound understanding relating to religious matters. He was involved in translating Indian treatises, which formed the only source of study for early Chinese Mādhyamika Buddhism. He also authored a small number of texts, but is famous for the book Zhaolun. Its chapters are as follows: Things Do Not Shift, Non-Absolute Emptiness, Prajna Is Without Dichotomizing Knowledge, and Nirvana Is Without Conceptualization.
He is mentioned in the Memoirs of Eminent Monks.
Sengzhao criticized earlier Chinese Buddhist schools for believing in being or non-being. He concluded that all dharmas are empty.
He composed a series of treatises published under the title Chao Lun or Zhao Lun, which was first translated (1948) into English as The Book of Chao by Walter Liebenthal, and later (1968) republished in a revised edition with the revised title of Chao Lun, the Treatises of Seng-chao. .
A number of other accounts exist concerning the life of Sengzhao, though they rarely shed any new light on his work or activities. The Weishou [a collection of canonical texts] accords Sengzhao preeminence among the eight hundred or so scholars gathered at Chang’an: “Daorong and his fellows were of knowledge and learning all-pervasive, and Sengzhao was the greatest of them. When Kumrajva made a translation, Sengzhao would always take pen in hand and define the meanings of words.
