Feng Shui Books
There are countless books on feng shui. Most of them are simple "self help" books how to become richt quick and happy with obscure "marriage corners" and where to put aquariums in order to make money fast. That has nothing to do with the ancient art, philosophy and science of feng shui and how to build, so that we humans may live in rooms and surroundings that support us in our health and happiness. Numerous books even misquote old master texts and put interpretations forward that have no relation to what feng shui is all about and what was meant by the masters.
Feng Shui literature that I think shows what Feng Shui really means:
