In "Volume of the Sky" is my summary of the "two-day first-class" art of war. The highest realm for practicing "two-day first-class" is the realm of "a thousand miles and one empty". In an empty world, nothing is known, nothing exists.
Of course, "emptiness" does not exist. Knowing nothing is also knowing, this is "emptiness".
People in the world often mistakenly realize that what they don't know is emptiness. In fact, this is not real emptiness, but a mist-like chaos.
There is the same truth in the art of war. If you don't understand the rules of the art of war, you cannot say that the art of war is "empty"; people will call this empty because of confusion, but in fact this is not real empty.
The samurai should understand the true meaning of the art of war accurately, and then practice diligently. When practicing this Dao, you must be clear and clear in your heart, sweep away all the perplexed minds, and practice with your mind and mind. You will become a torch, and your mind will no longer be dark and confused, and you will enter the realm of real emptiness.
Whether it is practicing Buddhism or experiencing the principles of world affairs, before reaching the end, everyone feels that their own experience and cognition are the most correct and best; however, once they observe with a normal mind, they will be based on the principles of heaven and earth. If you look at it, they actually have deviated from the true way because of their obsession.
The true Tao must recognize everything with a straightforward heart. Only by taking emptiness as the true way can we see the world and everything.
In the real emptiness, goodness has driven out all evil. There is wisdom, truth, and Tao in the heart, but there is still nothing.
