Four important works by Zhang Sanfeng (Three Peaks Zhang) are provided, along with commentaries:

• The Great Process for Refining the Elixir Treatise
• Verses on Seated Meditation
• The Sleeping Immortal
• Zhang Sanfeng's Commentary on Lu Zi's One Hundred Word Discourse

These four works of Zhang Sanfeng outline clear perspectives on the Taoist practice of Internal Alchemy, a unique and effective system designed for the development of health, longevity, and immortality. Zhang Sanfeng, a Taoist priest of the twelfth century, is not only credited with the creation of Tai Ji Quan, but with some of the greatest Internal Alchemy texts. He reportedly lived 170 years, from the late Song dynasty through the Yuan and into the early Ming dynasty. Zhang's life exemplified the Chinese ideal of a true "cloud wandering" immortal. His internal alchemy and meditation texts reveal not only his deep wisdom, but his great influence on Taoism and the teachings leading to immortality.
