There is a story in Zen circles about a man and a horse. The horse is galloping quickly, and it appears that the man on the horse is going somewhere important. Another man standing alongside the road, shouts, “Where are you going?” and the first man replies, “I don’t know! Ask the horse!” This is also our story. We are riding a horse, we don’t know where we are going, and we can’t stop. The horse is our habit energy pulling us along, and we are powerless. We struggle all the time, even during our sleep. We are at war within ourselves…We have to learn the art of stopping – stopping our thinking, our habit energies, our forgetfulness, the strong emotions that rule us.
