Intellectual knowledge exists in and of the brain. Because the brain is part of the body, which must one day expire, this collection of facts, however large and impressive, will expire as well. {But spiritual insight transcends death.}
He who stands on tiptoe is not steady. He who strides cannot maintain the pace. He who makes a show is not enlightened. He who is self-righteous is not respected. He who boasts achieves nothing. He who brags will not endure. According to followers of the Tao, "These are extra food and unnecessary luggage." They do not bring happiness, therefore followers of the Tao avoid them.
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.
He who, conscious of being strong, is content to be weak, he shall be the paragon of mankind. Being the paragon of mankind, Virtue will never desert him. He returns to the state of a little child.
