"The World Upside Down: Essays on Taoist Internal Alchemy" by Isabelle Robinet and Fabrizio Pregadio

"This book contains four essays on Internal Alchemy (Neidan) by Isabelle Robinet, originally published in French and translated here for the first time into English. The essays are concerned with the alchemical principle of "inversion"; the devices used by the alchemists to "give form to the Formless by the word, and thus manifest the authentic and absolute Dao"; the symbolic function of numbers in Taoism and in Internal Alchemy; and the original meanings of the terms "External Elixir" (waidan) and "Internal Elixir" (neidan)."
