The Tao Te Ching, the esoteric but infinitely practical book written in the sixth century BCE by Lao Tsu, has been translated more times than any work except the Bible. For centuries, artists, poets, painters, and even gardeners have used the Tao Te Ching as a source of inspiration and guidance. The Tao wall calendar features contemplative nature photographs, gracefully stylized Chinese calligraphy, and translations of the Tao Te Ching and Chuang Tsu's Inner Chapters.
