Correcting oneself is correcting the whole world. The sun is simply bright. It does not correct anyone. Because it shines, the whole world is full of light. Transforming yourself is a means of giving light to the whole world.
True wisdom is less presuming than folly. The wise man doubteth often, and changeth his mind; the fool is obstinate, and doubteth not; he knoweth all things but his own ignorance… To be satisfied with a little, is the greatest wisdom; and he that increaseth his riches, increaseth his cares; but a contented mind is a hidden treasure, and trouble findeth it not.
Every portion of body, mind, and spirit yearns for integration of yin and yang… Where ordinary intercourse unites sex organs with sex organs, angelic cultivation unites spirit with spirit, mind with mind, and every cell of one body with every cell of the other body.
