Changlu Zongze (died c. 1107) was a Buddhist monk of the Chan monastery. He is noted for writing the Chanyuan Qinggui, the "Rules of Purity" code of conduct in 1103, the earliest comprehensive book of monastic rules for Chan Buddhist monasteries. The short essay Zuochan yi, also attributed to Zongze, is the earliest guide to seated meditation in the Chan tradition.
He was raised by his mother, having lost his father (whose surname was Sun) at an early age. After studying Confucius at an early age he turned to Buddhism. He was tonsured at the Yunmen Temple at the age of 29 and then studied with Changlu Yingfu. Years later, he experienced a sudden awakening which he recorded in a poem, after which he was declared a Cijue Dashi (Master of Compassion and Enlightenment).
