Equanimity, good health, peace of mind, and long life are the goals of the ancient Taoist tradition known as "internal alchemy, " of which "Cultivating Stillness " is a key text. Written between the second and fifth centuries, the book is attributed to T'ai Shang Lao-chun--the legendary figure more widely known as Lao-Tzu, author of the "Tao-te Ching . " The accompanying commentary, written in the nineteenth century by Shui-ch'ing Tzu, explains the alchemical symbolism of the text and the methods for cultivating internal stillness of body and mind. A principal part of the Taoist canon for many centuries, "Cultivating Stillness " is still the first book studied by Taoist initiates today.
