Let me answer it for you. There is only one answer, and I'll solve it for you so you don't have to worry about it.
This world is false, illusory.
Mundane people, with their shallow wisdom, use their own physical senses to think that the material world that they can see and touch is real, and many of them will say quite righteously, "How can it not be real, I saw it, I touched it, he hit me, I will be in pain, I have a house, I planted two trees and they are now growing very well, is it not real?
From a mortal's point of view, most people on earth would think that the world is real, yet in fact the opposite is true, the world is unreal.
What is the reasoning?
This goes back to the truth of the universe.
The world we can see and perceive is called the colored world, and the world we cannot see or perceive is called the colorless world, which has no substance.
Whether it is the colorless world or the colored world, it is all the illusion of the Tao. The world is formed through karma, and when the karma is broken, the world will dissipate.
To make a simple analogy, an immortal is on a mountain and wants to sit on a chair. Because of this cause, he changes a chair, and when he finishes sitting on it, the chair loses its significance, and when he touches it with his hand, the chair disappears.
The world we live in was created due to a big "cause", and when the cause is broken, the world will collapse.
So it is said that our world is a false one, made up of karma.
And why is it that when I go to bite a rock and it doesn't move and my teeth crumble, it seems to really exist?
Is it? This is that mortals do not have the eye of wisdom without great wisdom, if a person has the eye of heaven, the eye of wisdom or the eye of Buddha, the world in his eyes, which is made up of clusters of colorful light, one can see that the world is false, it is made up of karmas and karma, and once the karmas are broken, the person will die and return to the embrace of the Tao or enter into the next karmas. Once the karma is broken, the world will also be destroyed because there is no more karma to sustain its continued existence. To use the most graphic analogy, your hands squeeze a pile of stones together, and when your hands no longer have a role to play in adding to the stones, the stones will separate and never come together again.
All of the above is professional opinion, right or wrong, you make up your own mind.
