"Horses are, in fact, natural Taoists. ... Taoism is best known in popular culture for the 'yin-yang' circle, its two interlocking tadpole-like symbols representing the balance of opposites in the universe and in the human psyche: white and black, light and dark, sound and silence, doing something and doing nothing. To the relentlessly assertive, patriarchal Western mind, the Taoist picture of reality at first appears contrary to everything we believe because it asks us to consider the opposite of our normal inclinations. One of the most famous quotes from the Tao Te Ching
advises us to 'know the yang, but keep to the yin,' which often appears in translation as 'know the masculine but keep to the feminine.' When I was with horses, I began to live this philosophy."
