It is because every one tinder Heaven recognizes beauty as beauty that the idea of ugliness exists.
LaoziThe good man is the teacher of the bad, And the bad is the material from which the good may learn. He who does not value the teacher, Or greatly care for the material, Is greatly deluded although he may be learned. Such is the essential mystery.
LaoziAct without doing; work without effort. Think of the small as large and the few as many. Confront the difficult while it is still easy; accomplish the great task by a series of small acts. The Master never reaches for the great; thus she achieves greatness. When she runs into a difficulty, she stops and gives herself to it. She doesn't cling to her own comfort; thus problems are no problem for her.
Laozi
