Yuan Zhongdao was one of the representatives of Buddhist studies for laypeople in the late Ming Dynasty. The article Chanmen Bencao Bu that he wrote used a pharmacological way to describe Buddhism, clearly showing his Zen philosophy in his later years. Although the article Chanmen Bencao Bu follows the form of Chan Ben Cao by Zen Master Huiri Wenya in the Song Dynasty, the Zen view expressed by it is completely different from Chan Ben Cao. It can be said that the article Chanmen Bencao Bu is mainly aimed at the directness of the Zen in the late Ming Dynasty, which only emphasized epiphany instead of gradual cultivation, and conveyed Yuan's concept of gradual cultivation of the unity of Zen and the Pure Land School.
