When I was attending a Chinese university to study traditional Chinese medicine 23 years ago, Feng Shui was part of the study program. We needed to study Feng Shui as diligently as other subjects.
Chinese medicine is a true holistic medicine based on prevention.
The goal is to maintain a high level of health spiritually, mentally and physically. These three levels of vibration are inter-related which means they cannot be dissociated or treated separately and one action, one level will have a reaction on another level. For spiritual health one can use meditation, prayer or contact with a superior level of consciousness. For mental health one can use the right way of thinking, and activation of the memory by study or mental exercises. For physical health one can use right food right exercises right breathing right environment Feng Shui works on all of these three levels but the easiest to understand and control is the physical level of vibration, which of course will affect the two other levels, mental and spiritual.
