"Ho's mastery of the history of science in China is awe inspiring...this is an extremely well-edited volume, with in-text Chinese characters, chemical formulas, and extensive cross-referencing. It will be an essential reference for scholars of the history of Daoism, alchemy, and Chinese science." - Bridie Andrews Minehan, ISIS, 100:1 (2009)"Based on solid scholarship in both the natural sciences and history of religions, this collection of articles by Ho Pend Yoke makes an invaluable contribution to our understanding of Daoist alchemy. It presents important materials, both from within the Canon and beyond, in their original wording and with careful examination of their provenance, editorial history, and traditional relevance. The scholarship is impeccable and the work most essential – providing access to materials otherwise hidden in the nebulous realm of Daoist alchemy and encouraging scholars to engage more actively in the interdisciplinary examination of traditional sources." – Livia Kohn, EASTM
