If a warrior is not unattached to life and death, he will be of no use whatsoever. The saying that "All abilities come from one mind" sounds as though it has to do with sentient matters, but it is in fact a matter of being unattached to life and death. With such non-attachment one can accomplish any feat.
Resolve your mental energy into abstraction, your physical energy into inaction. Allow yourself to fall in with the natural order of phenomena, without admitting the element of self,—and the empire will be governed.
Accept everything just the way it is.
This is the Way for men who want to learn my strategy: Do not think dishonestly. The Way is in training. Become acquainted with every art. Know the Ways of all professions. Distinguish between gain and loss in worldly matters. Develop intuitive judgment and understanding for everything. Perceive those things which cannot be seen. Pay attention even to trifles. Do nothing which is of no use.
These things cannot be explained in detail. From one thing, know ten thousand things. When you attain the Way of strategy there will not be one thing you cannot see. You must study hard.
People in this world look at things mistakenly, and think that what they do not understand must be the void. This is not the true void. It is bewilderment.
