Supreme Clarity Scripture of Golden Elixir 太清金液神丹经

Originally attributed to "the True Lord Yin of Longevity".

Comprising three volumes, it is included in the Methods category of the Dongshen Section of The Daozang.

According to Ge Hong’s Biographies of Immortals, Yin Changsheng of the late Han Dynasty studied under the True Lord Ma Mingsheng and received the three-volume Taiqing Scripture of the Divine Elixir.

In addition, Baopuzi: On Golden Elixirs records that Zuo Ci of the late Han Dynasty passed down the three-volume Taiqing Scripture of Elixirs to Ge Xuan, who later passed it to Ge Hong through Zheng Siyuan. Though these accounts cannot be fully verified, textual research by Chen Guofu indicates that this scripture had already appeared by the Eastern Jin Dynasty or the Liang Dynasty at the latest. The text focuses on external elixir alchemy, and its content can be divided into three parts. First is the preface, falsely attributed to the Celestial Master Zhang Daoling, with annotations by his disciples Wang Chang and Zhao Sheng. It discusses the practices of ingesting elixirs, regulating qi, and inner cultivation of guarding the One. Second is the main scripture, falsely attributed to Yin Changsheng. It includes two sections of heptasyllabic rhymed verses, as well as methods for preparing Liuyi clay, refining the golden fluid and reversible elixir, extracting essence from realgar and orpiment, and making frost and snow elixirs. All these sections list the medicinal formulas, utensils, and procedures for pounding and refining required for elixir-making. It is claimed that the golden fluid and reversible elixir refined in accordance with these methods can transmute lead into gold, and those who take it can ascend to immortality and "attain the freedom of transformation". The third part consists of accounts by Zheng Siyuan and Ge Hong. It includes the story of the Jin Dynasty figure Bao Jing encountering Yin Changsheng and receiving the transmission of Taoist methods, as well as the locations and products of more than twenty countries such as Funan, Xitu, the Roman Empire, Yuezhi, and Parthia. These countries were said to produce abundant cinnabar and immortal medicines, hence they were called "elixir-producing lands". It should be noted that this text is also included in Volume 65 of Cloudy Satchel of Seven Slips, but without the aforementioned third part. This scripture can be studied in conjunction with Baopuzi: Inner Chapters and serves as important material for researching early elixir alchemy, which is an integral part of Taoism practices. Its content regarding elixir formulas and material properties is closely associated with the five elements theory in traditional Chinese philosophy.
