The Mystic Knot is one of the most often used symbols in feng shui. Being a combination of six times the infinity symbol, this knot symbolizes a long and happy life full of good fortune. Mystic knot is sometimes referred to as the endless knot, because it looks like it swallows its own tail.
In Buddhism, the mystic knot is one of the 8 magical auspicious objects. This symbol implies there is no beginning and no end.
