Astronomy and Chen Zhixu’s Neidan Theory

[Paul Ferguson]

"Chen Zhixu (陳致虛), a prominent Taoist master of the Yuan Dynasty, significantly contributed to aspects such as the creation of Taoist genealogy and the theoretical interpretation of Neidan (内丹 internal alchemy studies). Astronomy of different aspects served as an important intellectual resource for him. Chen Zhixu not only explained the correlative cosmological model in traditional internal alchemy theories, but also introduced systematic calendrical knowledge to broaden the astronomical foundation of his theoretical propositions, thereby strengthening the connection between internal alchemy practices and astronomical research."
