Quotes about the realm of life: The highest realm of life is: Buddha is the heart, Tao is the bones, Confucianism is the expression, look at the world magnanimously; skills are in hand, energy is in the body, thoughts are in the brain, and life can be lived calmly . Reading history for three thousand years is nothing more than fame and wealth; enlightening for ninety thousand miles will eventually lead to poetry and wine.

Quotes about culture: Ancient Chinese did not write articles easily. Many articles, dramas, and news today write about the bad side of society and have a very bad impact on children. This kind of writing has a greater impact on society than killing people. In fact, the people who write may not have the intention to teach people to do bad things, and some write positive things, but the people who accept them don't see the positive side. The ancients understood this human psychology very well, so they wrote very rigorously.

Famous quotes about everything: Everything in the universe must have its reason. If there is such a thing, it must have its principle. It’s just that we don’t have enough wisdom and experience to find the reason. I don’t understand its principle. The simplicity of the "Book of Changes" is also the highest principle. No matter how mysterious things are in the universe, when we are wise enough and understand them, they become ordinary, the most ordinary and very simple.
