He who gains a victory over other men is strong; but he who gains a victory over himself is all powerful.
LaoziThus an army without flexibility never wins a battle. A tree that is unbending is easily broken.
LaoziHe 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.
