Today's world is a restless world. "The world is bustling, all for profit; Everything in the world is beneficial. " In such a world, our hearts are often in an "impulsive" state, sometimes moved by "fame", sometimes by "profit" and sometimes by "color", and our thoughts come and go. These distractions sometimes worry you, sometimes worry you, sometimes make you angry, and sometimes bother you. Sometimes you want to forget some unpleasant things in your life, but you just can't forget them, and even let you sit down and think, while walking, while eating and while sleeping. As Wang Yangming said, "The more you are interested in seeking peace, the more restless you are."

"Don't stay once" is a state, which means that you can let your thoughts pass through your heart without stopping. The clarity of the heart is not the absence of thought, but the inability to live without thought. Yang Ming said that the mirror should be real, and it won't stay after it. "If you don't stay, there will be no place to live." Huineng, the sixth ancestor of Zen Buddhism, said, "The Tao must flow, so why should it stay?" If the mind can't live in Dharma, the Tao will flow; If the heart abides in the law, it is called self-restraint. "Zhuangzi said," the heart is like a mirror. Don't hide it if you don't welcome it. "As can be seen from the above, Confucianism, Buddhism and Taoism have different opinions, but the truth is the same. They all believe that a wise man's heart is like a mirror, and he can respond to the outside with his heart, so that the generated thoughts will "flow through" in his heart, but will not "stay" in his heart, or "live" or "hide" in his heart. Only in this way can we keep a clean heart, not be tired or hurt by other thoughts, and enjoy quiet pleasure.
