“The man who is saturated with Virtue is like a little child. Scorpions will not sting him, wild beasts will not seize him, nor will birds of prey pluck at him. His young bones are not hard, neither are his views strong, yet his grasp is firm and sure. He is full of virility, though unconscious of his sex. Though he should cry out all day, yet he is never hoarse. Herein is shown his harmony with Nature. The knowledge of this harmony is the eternal Tao. The knowledge of the eternal Tao is illumination. Habits of excess grow upon a man, and the mind, giving way to the passions, they increase day by day. And when the passions have reached their climax, they also fail. This is against the nature of Tao. What is contrary to Tao soon comes to an end.”
