This symbol is called "world triad". Originally an oriental symbol, it was adopted by westerners as an emblem of cosmic creativity, the threefold nature of reality or fate, and the eternally spiraling cycles of time. In Japan it is the maga-tama or mitsu tomoe, the world soul. In Bhutan and Tibet, it is known as the cosmic mandal, a sign of the Trimurti. Like the yin yang, it also represents eternity. I chose it because to me, this symbol represents my three kids.
