“1 It is of great interest, in this regard, that the five-part taijitu (referred to in Chapter 1 and the source of the simpler yin/yang symbol) expresses the origin of the cosmos as, first, originating in the undifferentiated absolute, then dividing into yin and yang (chaos/order, feminine/masculine), and then into the five agents (wood, fire, earth, metal, water) and then, simply put, “the ten thousand things.” The Star of David (chaos/order, feminine/masculine) gives rise in the same way to the four basic elements: fire, air, water and earth (out of which everything else is built).”
