Yin and Yang are spiritual forces in Chinese philosophy. Together they form the life-giving power of the universe, but apart they are opposite sides of the pole. Yin is the moon; the soft, the feminine, the receptive and even side of things. Yang is the sun; the bright and powerful masculine force, the odd and wild side.

There are meat eaters, vegetarians, and vegans. Vegetarians drink milk and eat dairy products. Vegans eat no animal products.

Meat eaters and vegetarians are the Yang. By eating animal flesh or drinking their body fluids, one ingests their hormones. Vegetarians often drink more milk and eat more dairy than meat eaters.

Vegans eat no animal hormones. Vegans are the Yin.
