“A human being has so many skins inside, covering the depths of the heart. We know so many things, but we don't know ourselves! Why, thirty or forty skins or hides, as thick and hard as an ox's or bear's, cover the soul. Go into your own ground and learn to know yourself there.”
“If you seek the kernel, then you must break the shell. An likewise, if you would know the reality of Nature, you must destroy the appearance, and the farther you go beyond the appearance, the nearer you will be to the essence.”
