Changlu Zongze

Changlu Zongze (died c. 1107) was a Chinese Chan Buddhist monk noted for writing the Chanyuan Qinggui, or The Rules of Purity in the Chan Monastery. Written in 1103, it was the earliest comprehensive book of monastic rules for Chan Buddhist monasteries.

Little is known about him, but the influence of his work was significant and he is exalted in the Pure Land documents as one of the patriarchs of the Pure Land lineage. 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).
