Philosophically, external causes work through internal causes. Feng Shui is the external cause, but what is the internal cause? The internal cause is your own internal magnetic field, that is, your own heart. In Buddhism, all laws are born of thoughts. So, if you are kind, you can feel a good magnetic field outside. A beautiful marriage will naturally follow.
Finally, Feng Shui, whether it is numerology or horoscope, belongs to branches and leaves, while Buddhism is fundamental and the ultimate wisdom of life in the universe. Can explain all the life phenomena in the universe. The eight characters of Feng Shui and Buddhism are the relationship between tolerance and being tolerated. There is no opposition, only unity. In Buddhist terms, one is not two.
