Nature always wears the colors of the spirit. To a man laboring under calamity the heat of his own fire hath sadness in it. Then there is a kind of contempt of the landscape felt by him who has just lost by death a dear friend. The sky is less grand as it shuts down over less worth in the population.
What is God-given is called nature; to follow nature is called Tao (the Way); to cultivate the way is called culture. Before joy, anger, sadness and happiness are expressed, they are called the inner self; when they are expressed to the proper degree, they are called harmony. The inner self is the correct foundation of the world, and the harmony is the illustrious Way. When a man has achieved the inner self and harmony, the heaven and earth are orderly and the myriad of things are nourished and grow thereby.
What is the source of sadness, but feebleness of the mind? What giveth it power but the want of reason? Rouse thyself to the combat, and she quitteth the field before thou strikest.
On Man, on Nature, and on Human Life, Musing in solitude, I oft perceive Fair trains of images before me rise, Accompanied by feelings of delight Pure, or with no unpleasing sadness mixed.
There is a sadness at the back of life which some people do not attempt to mitigate. Entirely aware of their own standing in the shadow, and yet alive to every tremor and gleam of existence, there they endure.
The point is not that this world is too sad to love or too glad not to love; the point is that when you do love a thing, its gladness is a reason for loving it, and its sadness a reason for loving it more.
When sadness comes, just sit by the side and look at it and say, "I am the watcher, I am not sadness," and see the difference. Immediately you have cut the very root of sadness. It is no more nourished. It will die of starvation. We feed these emotions by being identified with them.
Thoughts are no more than electrical surges in the brain. Sexual arousal is no more than a flow of chemicals to certain nerve endings. Sadness is no more than a bit of acid transfixed in the cerebellum. In short, the body is a machine, subject to the same laws of electricity and mechanics as an electron or clock.
