Jizang （549-623） A Sanlun master， whose parents came from Parthia. He became a novice under Daolang 道朗 at the age of seven， and as he grew up， he became renowned for his extensive learning， especially concerning the Ma^dhyamika 中观派 school. He lectured on Ma^dhyamika scriptures and wrote commentaries on them， thus consolidating the foundations of the Sanlun sect 三论宗. As he lived for some time at Jiaxiang Temple 嘉祥寺， he was popularly called the 'Great Master Jiaxiang.' His Sanlun xuanyi 三论玄义 （'Essentials of the Three Treatises'）， one fascicle， is a useful compendium of the Sanlun doctrine. He also wrote three commentaries on the Lotus Sutra.
