There is a stele named Biography of Liu Benzun of the Tang Dynasty remaining at Baoding Mountain, 
Dazu. In Dazu and the neighboring Anyue area, there are three sets of Ten Austerities, mainly depicting the 
cultivation and preaching activities of Liu Benzun, a lay Buddhist of the Esoteric School in the late Tang Dynasty 
specializing in the Five-Part Esoteric Dharma of the Great Wheel and skilled in treating diseases with religious 
means such as talismans and incantations. He had a wide social influence in the western Sichuan region at that 
time. Liu Benzun’s medical and preaching activities reflect the reality of Buddhist monks promoting Buddhism through medicine under the complex political situation in the late Tang and Five Dynasties period, and reveal the development of Buddhist medicine and local religions since the Tang Dynasty, which have significant historical value.
