One of the most difficult tasks to accomplish in life is to separate shadow from substance. Most of our life, we keep confusing one with the other, and battling against we know not what. There are times when we take shadows for real and times when reality seems but a shadow. The wise ones of course know that the entire drama is no more than a play of light and shade on our senses. The wise one do not try to separate one thing from the other. They love the hide and seek.
