The correct statement is: some people know this world, but some people really don't know it.
Why? This is about the nature of the universe and life. As we know, Einstein's intelligent equation shows that mass and energy are unified and a mutual transformation system. From this, we can easily understand that everything in the universe, including life, is essentially a kind of energy, and life is different because of its different energy structure.
Since people are a kind of energy, when people pay attention to a thing with their thinking, they actually use energy to interact with it, which will lead to friends' problems and change the state of things. So for ordinary people, the truth of this world is hard to be perceived.
However, we know that there are practitioners all over the world. Believe it or not, ordinary people are firmly pursuing the legacy of the sages, pursuing the truth of the universe and life through the road of practice, and finally reaching the sublimation of life. Almost all practice methods require practitioners to be quiet and have no desire, and finally reach the realm of ignorance and no desire. At this time, all the moving energy in the universe will disturb the life of the yogi, and the whole living space of the yogi is static, so it is very easy to perceive the disturbance of this energy, so as to understand the true face of the universe.
Therefore, the world is knowable, but it is unknowable. Life is extremely magical, but on the surface it is ordinary.
