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.
My teachings are easy to understand and easy to put into practice. Yet your intellect will never grasp them, and if you try to practice them, you'll fail. My teachings are older than the world. How can you grasp their meaning? If you want to know me, look inside your heart.
