Living in the US and in California my first contact with Feng Shui was finding the book "The Western Art of Feng Shui". I liked the book it made a lot of sense and I realized that I had been practicing Feng Shui without even realizing it. Then I found Thorstons "Principles of Feng Shui" which was harder to read and comprehend but a good reference book. I picked up a video on Feng Shui and have watched that a lot and find it helpful. The author shares some of his experiences with his consultations shows the changes he suggested. What do you think is the best book to read?

Thank you for your study material suggestions and cautions on the "black hat" sect.
