《周易参同契》 (Zhou Yi Can Tong Qi) is a Taoist Classic regarding the principles and methods of self-cultivation for enlightenment and longevity. On the surface, one may think that the Classic has little or no correlation to Fengshui.

Fengshui literally means nature’s "Wind" and "Water".  To have a better understanding of Fengshui, one must first understand the Principles or Way of Nature; or "道".  Simply put, "道" can have three different meanings to it, the "Way of Religious Taoism" or 道教之道, "Way of Philosophical Taoism" or 道家之道 and "Way of Fengshui" or 风水之道.
