Without opening your door, you can open your heart to the world. Without looking out your window, you can see the essence of the Tao. The more you know, the less you understand. The Master arrives without leaving, sees the light without looking, achieves without doing a thing.
Simply see that you are at the center of the universe, and accept all things and beings as parts of your infinite body. When you perceive that an act done to another is done to yourself, you have understood the great truth.
Therefore: In dwelling, choose modest quarters, in thinking, value stillness, in dealing with others, be kind, in choosing words, be sincere, in leading, be just, in working, be competent, in acting, choose the correct timing. Follow these words and there will be no error.
