Baopuzi is the text by Ge Hong that records Taoist methods of alchemy, health, and immortality.
Ge Hong, also known as Ge Zhichuan, wrote the work in the Eastern Jin period, probably during the fourth century CE. Its title is often translated as The Book of the Master Who Embraces Simplicity. Ge Hong presented himself as a follower of earlier Taoist traditions while also discussing medicine, religious practices, talismans, and techniques intended to prolong life.
The work is divided into an inner section and an outer section. The inner chapters focus mainly on religious and alchemical subjects, while the outer chapters discuss ethics, politics, literature, and historical topics. This division makes Baopuzi valuable both for the history of Taoism and for wider knowledge of early medieval Chinese culture.
Baopuzi is sometimes confused with the Huainanzi, an earlier Han-dynasty text associated with Liu An. The two works both discuss cosmology and techniques of self-cultivation, but they belong to different periods and have different authors.
