The Tao that can be trodden is not the enduring and Unchanging Tao. The name that can be named is not the enduring and unchanging name.' So begins one of the most important spiritual books on the planet. The Tao Te Ching, the second most translated book in the world, was written by the father of Taoism, Lao Tzu. It contains a series of maxims, sayings, or truths, which are best absorbed slowly, over a period of time. Anyone with an interest in personal or spiritual growth should own a copy of this book. Its worth is immense.
