Book excerpt: The book "Fabulous Principles of Feng Shui" is based on the study of the authors dealing with traditional sciences of architecture and more specifically Feng Shui as an esoteric view towards the science of built space. Since there are many models of Feng Shui being practiced today, which provide controversial theories regarding concepts and principles of this science, the authors have tried to introduce the more universal approach that can be used by a wider range of people. During this study, a number of differences between the practices introduced in Vastu Shastra and Feng Shui were noticed which are believed to be due to the environmental issues or cultural behaviors, especially regarding the knowledge of directions, slopes, etc. Therefore to have a thorough knowledge of the best energetic formation for architectural spaces, it is highly recommended to study the book "Amazing Principles of Vastu Shastra." This book basically introduces the principles behind the science of Feng Shui as practiced today.
