Human life is short, everything is impermanent, impermanent, like a cloud floating in the sky, leaving in our hearts so many worries, regrets and fears. The string of time silently passed until death knocked on the door and left, leaving the mourners to see them off. “All things in the world that are subject to change and decay are impermanent.” So impermanent means impermanent, not stable, from one state to another change and dissolve according to the law of becoming, staying, breaking, not being born, standing, changing, and passing away. For example, a wave, when newly emerged, is called a citadel (or birth). When it rises the highest is called a pillar. When descending, it is called destruction (or hetero). When it disintegrates, it is called emptiness (or cessation). Thus, all things in the universe, from as small as a grain of sand to as large as the moon and stars, are subject to those four stages, so they are called impermanent. 1. Body impermanent: Speaking of impermanent body, it is born and dies every moment and then the time chain will silently push us into death. According to today's scientific fact, it has been proved that the cells in the human body are always changing, making us grow quickly, age quickly and then die. The human body is like the snow on the branches, the dew on the grass, only to see it and then disappear. Not everyone is free from birth, old age, sickness, and death. Since she was still in the mother's womb, she has suffered, the four sides are covered with darkness like a prison full of uncleanness. From birth to adulthood, experiencing countless illnesses, accidents, melancholy, suffering... always lurking around. Age in the afternoon is even more miserable: wrinkled skin, gray hair, sunken cheeks, lost teeth, thin body, difficulty walking, constant illness, unspeakable suffering, step by step into death. But when we leave the temporary life, we only follow the path of sin. Speaking of death, in the Sutras forty-two Chapters, it is said that: When the Buddha was in the world, one day he called for the monks to come and ask: - How long does a human life last? The first said: - World-Honored One, human life is 100 years. The second said to live 70 years, and the third said to live only a few days. Finally, one person stood up and said: - World-Honored One! Human life is within the breath. The Buddha praised that: - He understood and said so that he is truly an enlightened person. Our body borrows external conditions to survive. When fate ends, it disintegrates. When impermanence comes, we know that we are in a dream, everything is impermanent. Only good or bad karma remains. 2. The mind is impermanent: The body is impermanent, but is the mind impermanent? Speaking of the mind, it is much more impermanent than the body. It arises and passes away very quickly, every moment, every thought. Whenever facing the scene, the mind is happy, sad, hateful, angry. Sometimes it's time to reminisce about the past to regret. While dreaming of the future. Restless anxiety in the present, there is no time to rest. It changes constantly, undulating like waves in the sea, so the Buddha called it the mind of a horse (such as a monkey passing branches, a horse running around). Ordinary people mistakenly accept their own mind as real and cause countless mistakes, whether it is domineering, obstinate, proud, boastful or threatening, saying: "My personality is very hot, please don't touch me. ". The nature of anger, delusion, aggression, evil like that without knowing how to correct it, even speaking out, is really stupid. Mind is impermanent or disturbed, it creeps into each person's life, whether ordained or at home. In the Dhammapada, the Buddha taught: "A wise person guards his mind Like a fortress guarding a fortress. His own mind should also be protected like that. Even if it's only for a moment, it shouldn't be loose. Immediately fall down." So what is mind protection? That we have to subdue the six senses (eyes, ears, nose, tongue, body, mind). In the A-ham Sutra, the Buddha offers 11 methods of practice for the mind to be peaceful and liberated: 1. Being yourself a good friend, close to a good friend, to learn the right things. 2. Must keep the precepts forbidden, capture the posture, protect the apartments, even if it shows a small error, it is also feared. 3. Good thing that has not yet been born makes it born. The good that has arisen causes it to grow. Evil has not yet arisen, do not let it arise. Evil that has already arisen must be eliminated. 4. Do not gather around the table to talk useless nonsense, illegal. Whenever he speaks, he must speak according to the law, always praising and praising the virtues of lack of sexual desire and tri-content, talking about precepts, concentration, wisdom, and liberated knowledge. 5. Contemplation of impure body. 6. Contemplation of the mind impermanent. 7. Contemplation of no-self. 8. Quan life of suffering. 9. Shop instant book. 10. Tu heart from the heart. 11. Tu impermanent thought. In short, all dharmas are created by the mind. While doing whatever you want to do, you need to take wisdom and think about it. If such speech or action brings benefits to oneself and others, efforts should be made, but if it causes harm to both or benefits others, it must be eliminated. To have clear wisdom, it is important that the mind is pure, self-aware and good-natured, and must be close to good people, try to keep the precepts, and protect the senses. When we speak, we must speak according to the Dharma and speak ethically, actively do good deeds, contemplating our own body as impure, and material things as temporary. mind is not real, dharma is only a means, which means seeing and knowing all without being contaminated, clinging to that is the mind of truth, bliss, and freedom. This is a method of sesshin to maintain mindfulness, purifying reflection, making the mind pure and pure. Movement, purity, suffering, joy, good or bad environments and circumstances around us are all created by the mind. 3. Circumstances impermanent: As we have also seen and witnessed, there are countless scenes of honor and disgrace, high and low, gain and loss, more and more loss that continues to take place before our eyes. There are houses, cars, material possessions full of chests, but even an earthquake, natural disaster, fire, storm, flood or a mutiny becomes ashes. , rubble buried deep into the ground. Impermanence is the law governing all things from the body, attentive to all circumstances. Understanding impermanence, we will have a magical remedy to eliminate the disease of craving and confusion. We have suffered because of good and bad colors, because of good or bad reputation, because of sweet and bitter taste, because of pleasing things. Now we take the medicine "the teaching of impermanence" to get rid of the disease of craving and progress to peace of mind. Knowing impermanence, it is easy for people to remain calm, indifferent to unexpected changes and can be cold before the scene of love and separation. Knowing impermanence, people dare to sacrifice property and life to do good deeds. Knowing impermanence, people are bored with temporary, false pleasures and are wise to look for true, permanent joys. Because in fact, the true joy is always there, the true nature is still there, but it is inside the temporary layer so we can't see it.END=NAM MO SHAKYAMUNI BUDDHA.( 3 TIMES ).BUDDHIST DHARMA WHEEL.GOLDEN AMITABHA MONASTERY=VIETNAMESE BUDDHIST NUN=THICH CHAN TANH.AUSTRALIA,SYDNEY.7/7/2021.VIETNAMESE TRANSLATE ENGLISH BY=VIETNAMESE BUDDHIST NUN=THICH CHAN TANH.
