Geomancy, also known as feng shui (the Chinese version) is a science which analyses the subtle energies of nature that ebb and flow throughout the landscape, influencing health and wealth; home, garden and office alike.
Every culture has ancient geomantic traditions. Modern scientists speak of Earth's geobiology.
People long ago learned to avoid places that had noxious energies. Where the Earth spirit was potent or sublime they would gather for spiritual practises, later temples and churches were built there.
