Written more than two thousand years ago, The Scripture on Tao and Virtue is a guide to cultivating a life of peace, serenity, and compassion. It is the foundational philosophical work of all Taoism and one of the true classics of spiritual literature. Usually translated as the "Way", the Tao is the mysterious process through which everything in the Universe happens.
The Tao Te Ching is actually the second-most translated book after the Bible.
