When you understand the impermanence of fame and fortune, once you lose it, you won't feel the world is broken; when you understand the impermanence of feelings, you will not seek life or death when encountering changes; when you understand the impermanence of life, you can face the death of your loved ones calmly. Nothing in the world is absolutely static, all of which are in motion and change. This is what Buddhism calls 'Impermanence'. Because of impermanence, our happiness cannot be forever, it can become pain at any time. For example, the 'Four Hundred Theory' says: 'Impermanence is detrimental, and damage is not happiness. Therefore, if impermanence is impermanent, everything is suffering. 〃Any impermanence is bound to perish; as long as it perishes, it is not. Real happiness. Once upon a time, there was a beautiful princess, and my father loved her very much. Whatever she wanted, my father would try to satisfy her. It rained heavily one day, and the water in the palace yard splashed many blisters. The princess loved her very much when she saw her. So he asked his father: 'I want to use that bun to wear it into a bun and decorate my hair. 'The king said: 'This is impossible. 'The princess played coquettishly and committed suicide if she said she couldn't get it. The king was terrified, so he had to summon craftsmen from all over the country and order them to make blisters for the princess. Many young craftsmen had nothing to do about it, and they were particularly distressed. At this time, An old craftsman said he had a way. The king was very happy and asked the princess to be the 'supervisor' himself. The old craftsman said to the princess: 'I only wear buns. I don't know the beauty and ugliness of blisters. Please choose the princess by yourself. After the selection, I can dress you as a bun.' The princess happily went to choose blisters. After working for a long time, I didn't get any of them. Finally, she was so exhausted that she turned around and ran into the palace and said to her father: 'Although the blisters are very beautiful, they can't be retained even when they are in the hands. This is undoubtedly a kind of foolishness. The suffering of the world comes from the attachment of various measures. If you can understand the principle of impermanence and not be too attached to everything, the pain will not be so intense. For example, when you understand the impermanence of fame and fortune, once you lose it, you won’t feel that the heavens will fall apart; when you understand the impermanence of emotions, you will not find life or death when encountering changes; when you understand the impermanence of life, you can face the death of your loved ones calmly. In times, there was a woman whose husband abandoned her, and her only child died again. The woman was desperate to have a child and came to the Buddha with the corpse of the child. He prayed for the Buddha to show mercy and save the child anyway. Otherwise, She doesn't want to live in the human world. The Buddha said: 'It is not difficult to save your child, but you have to ask for a mustard seed from a family that has never died. Give this to me, and I can save the child. 'This woman went from house to house, but no one had never died before. Finally, she finally understood: People are always going to die, and death is very equal to everyone. So the death of a child is not so much. Can’t let it go. The ancients also said: 〃There are cloudy, sunny, and vacant in the moon, and people have sorrows and joys. 〃 This is the law of impermanence, and no one can surpass it. If you can master this point, your life will suddenly become brighter, and any changes will occur. If you suffer any blow, you will not lose your mind.
