What enlightenment have you got from your understanding of the three realms of life?

Seeing mountains is not mountains, and seeing water is not water; See mountains or mountains, see water or water. Follow-up: I know these three realms, and I ask about the understanding and enlightenment of the realm. Hard work ~ ~ ~ Answer: There are three realms in life, which can be explained by a language full of Zen machines. This is: "Look at the mountains and see that water is water. Seeing mountains is not mountains, and seeing water is not water. See mountains or mountains, see water or water. In other words, a person's life is pure at the beginning. When he meets the world for the first time, everything is fresh, and what his eyes see is himself. People told him it was a mountain, and he knew it. Tell him it's water and he'll know. As you get older and experience more and more things, you will find problems in this world. There are more and more problems in this world, which are becoming more and more complicated. Often black and white are upside down, right and wrong are confused, and it is unreasonable to travel all over the world. If it is unreasonable, it is difficult to move. Good people are not rewarded, and evil people live for a thousand years. At this stage, people are angry, unfair, worried, questioning, alert and complicated, and people are unwilling to believe anything easily. At this time, people look at the mountains and sigh, look at the water and sigh, and use the ancient to satirize the present, pointing at mulberry trees. Mountains are no longer pure mountains, and water is no longer pure water. Everything is the carrier of people's subjective consciousness. The so-called good wind, with its strength, sent me to Qingyun. If a person stays at this stage of life, it will be a bitter life. People will see the heights of mountains, keep climbing, be competitive, keep up with others, how to be a man, how to do things, and live a life of endless satisfaction. Because the world is a circle, there are people outside, there are days outside, and the cycle is endless. And human life is short and limited, where will you care about eternal infinity? Many people reach the end of their lives when they reach the second realm. Pursue for a lifetime, toil for a lifetime, be arrogant for a lifetime, and finally find that you have not reached your ideal. So, hold a grudge for life. However, some people finally promoted themselves to the third realm of life through their own cultivation. Enlighten and return to nature. At this time, people will concentrate on doing what they should do and leave others alone. Let you roll in the world of mortals, and I will be cool and hearty. In the face of worldly things, laugh it off and forget it. At this time, people look at the mountains and see the mountains. Water is water. Exactly: "People are human beings, so you don't have to be a person deliberately;" "The world is the world, don't be careful to deal with; It is also a real life and work.
