Feng Shui (Shui means water/ Feng meaning wind) is very much a discipline that recognizes the importance of water in our lives. Ancient Feng Shui was a practice that involved finding the best location of land for monarchs and noblemen to build their houses: a house by the foot of the mountain with two streams of water on each side running toward the sea/ a pond was considered an ideal house, in “the belly of the dragon”. On the contrary, a house that sat on a well or on stagnant water was considered to have bad Feng Shui. Translated to present day, living on a boat full time is considered to be dangerous to physical and mental health.
In classical feng shui and ancient vastu, placement of water features such as wells, septic tanks, bathrooms, etc was very important from the hygienic perspective which now is less important since building processes and technology allowed for safer structures. For example, some people believe (incorrectly) that bathroom in the northeast part of the house is bad feng shui or vastu. In the old days, in most places in the western hemisphere northeast part of the house would be the coldest, hence there is a danger of mold and dump. Modern houses usually don’t have that problem any more. The general rule of thumb is to use water interventions for career and wealth creation. For specific use of the water features in your home or workplace ask your feng shui consultant.
