There are eight famous immortals (including Lao Tzu), referred to simply as the Eight Immortals. Each of them is unique in his or her background, style of life and in their practices for approaching the Tao. Yet, they all share a commonality of experience as they evolved into the oneness of the eternal, immortal, universal void of the all-encompassing Tao. The thrust of this book is directed to the practical significance and ramifications of cultivating the Tao and Te, regardless of the exercises one may employ for training. The authors affirm that mindfulness and cultivation of Tao and Te streamlines the effectiveness of all that we are and all that we do.

A collaborative work, Door To All Wonders contains some descriptions of, and references to, Taoist practices. Master Huang has laid the foundation of the text with his commentary and practical information related to Lao Tzu's Tao Te Ching, while Master Chia has provided complementary perspectives and practices refined from his extensive experience of teaching people from all over the world.
