Gewu Zhizhi first came from the Western Han Dynasty Dai Sheng's "Li Ji And University". It means to deduce the principles of things and thus acquire knowledge.
In fact, there is no certainty about the meaning of the knowledge of the lattice object. Different people have different understandings of the knowledge of qualities according to their own cultivation and the direction of their understanding.
Personally, I agree with Lu Jiuyuan's views. That is, when a thing is lattice, the thing itself is removed and the heavenly truth contained in the thing is obtained.
Now, from my own point of view, I try to "grid" an object, just "grid" a pen. Where did the world's first pen come from? Of course it is made by people. So what is this person based on? It was the imagination in his head. So you see, something out of nothing was born out of nowhere. There is nothing that cannot be done, only the unexpected, is not quite interesting.
Then I'll "check" a table again. I slammed my fist on the table, and my hand hurt. At this point we may immediately think of physical and reactionary forces. That's the rational explanation, and now we're going to explain it on a perceptual level – I hit the table, and the table hit me, so I feel a pain in my hand. This is a kind of feedback that we can actually feel, so what about what we can't feel? For example, you are very angry with a person, full of resentment towards him. Then you send out a resentful energy to him. Does he know the energy of this resentment? As if I didn't know. But the energy of this resentment has been emitted, can it disappear? According to the law of conservation of energy it does not seem to disappear. So where did it go? It may become a negative energy of others that is fed back into your heart. But you can't see it, and you can't perceive it.
Isn't it interesting for you to look at the lattice objects? Perhaps everything is born out of nothing in the final analysis, and its essence is "emptiness". As one of the famous enlightened verses of Master Huineng of the Six Patriarchs of Zen Buddhism in China said, "Bodhi has no tree, nor is the mirror a platform, there is nothing in the original, where there is dust." ”
Therefore, life is like a dream, after all, it is just an illusion. If we can attain enlightenment, we will no longer cling to the pursuit of things that do not exist in themselves, and will no longer cause troubles and sufferings.
A golden key to open the door of wisdom. It allows us to see clearly the heavenly truths implicit in these things through some ordinary small things, which is of great benefit to our lives. Now, let's try your hand at it and see what magical discoveries will be made?
