First, the human body is rare.
Very easy to understand. People are reincarnated in the three realms, but it takes 100 years and 1000 years to cultivate a human form in reincarnation. Because of karma, it is difficult to get a person in reincarnation, and it takes a lot to train a person. This is the "personal rarity" from the perspective of employment.
From the point of view of cultivation, animals are not allowed to practice, only people can practice. This is the legal principle of the universe. Because animals have no humanity, they must be "demons". Therefore, once every 300 years, a small robbery, once every 500 years, if you want to kill them, animals are not allowed to farm and breed. From this perspective, the "Fahai" in the legend of the White Snake is actually protecting the laws of the universe. This also explains "personal rarity" from another angle.
Second: real laws stink.
Master said: "In a very high realm, life is simple, the mind is simple and pure, but wisdom is great. Then come down, and you will have the duality of living and dying together. Further down, it becomes two different material factors. Because the celestial bodies in the universe are very big, when they come down, two different substances gradually oppose each other.
Further down, the different characteristics of two different antagonistic substances become more and more obvious, and there are positive and negative life forms. Then there are Buddha (French king) and devil (devil king), and there are many opposing factors, such as Yin and Yang, Tai Chi and so on. Further down, the principle of mutual resistance will be biochemical, and the contradiction between two different substances will become more and more serious. Because there are two opposite substances in the material composition, everything embodies Buddha nature and magic nature at the same time, which is why Buddhism says that "all beings are Buddha", but what it really says is that "all beings have Buddha nature".
Since there is mutual restraint in the world, there must be evil laws when Buddhism is preached. There are seven other religions that spread the Buddhism of Sakyamuni, and Brahmanism is the most powerful one. Laozi's teachings were disturbed by the appearance of a hundred schools of thought contending, which is what Master said: "Things are muddy and the pearls are mixed. If you come to the next life, you will be quiet. When you preach Buddhism, there must be evil interference. Taoism and the devil share the same life, true or false. Anyway, there must be a staff sergeant.
Sure enough, those who are destined to be enlightened, the two of them came one after another and learned the truth. Knowing right and evil, you can gain the true classics, ignore your body, enrich your wisdom, fill your heart, and take a leisurely boat. Very good! Strive for perfection until it is completed. People who are difficult to understand in the world live for money, die for power, enjoy and worry about petty profits, struggle all their lives and make achievements all their lives.
A person will laugh when he hears the law, and the word superstition is hard to believe in his heart. It is difficult for such a person to be a corporal. Industry has closed its body, closed its wisdom, and its nature is gone. The principle of mutual development and mutual restriction makes the "true law" and "evil law" mixed, depending on which door you enter. Therefore, the Dharma is actually very unpleasant, and only the Dharma can make you complete.
2,500 years ago, the object of Sakyamuni Buddhism was actually the most simple and virtuous person who had just been born from primitive society. The "Arhat Law" he preached violated the fundamental of people at that time, that is, to seek personal liberation. In fact, Sakyamuni's Buddha has a deeper Buddhism, and he can't take the road of nirvana, but he just doesn't preach it. Because the universe has the law of "birth, aging, illness and death", human morality will also follow the law of the universe, from moral nobility to moral decay.
