Kneel down and ask the man of God to see the meaning of this geomantic symbol.

This is something from Tibetan Buddhism.

Buddhism generally doesn't care about feng shui. Because feng shui is the law of the world, people have the heart to distinguish between good and bad in the world. This goes against the Buddhist view that everything is empty. Although there are people in Buddhism who use geomantic omen to attract attention, geomantic omen belongs to Taoism after all, not Buddhism.

This symbol is a good symbol and can be worn. But this has nothing to do with feng shui.
