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.
When I reached thirty I looked back on my past. The previous victories were not due to my having mastered strategy. Perhaps it was natural ability, or the order of heaven, or that other schools' strategy was inferior. After that I studied morning and evening searching for the principle, and came to realise the Way of strategy when I was fifty.
The lion who breaks the enemy's ranks is a minor hero compared to the lion who overcomes himself.
It is not the mountain we conquer, but ourselves.
