Yin and yang

---

According to macrobiotic philosophy, the infinite universe manifests in two antagonistic but complementary forces, yin and yang. Yin and yang represent relative tendencies that constitute and animate life.

In the macrobiotic delineation, yin is experienced as being more expansive, upward and outward, and yang as more contracted, downward and inward. In temperature, yin is colder while yang is hotter. In size, yin is bigger and yang is smaller. Yin is slower in movement and yang is more active. The heavenly body of yin is the moon and that of yang is the sun. The colours of yin are purple, blue, green and white, and the colours of yang are red, brown, orange and yellow.
