Even if you strive diligently on your chosen path day after day, if your heart is not in accord with it, then even if you think you are on a good path, from the point of view of the straight and true, this is not a genuine path. If you do not pursue a genuine path to its consummation, then a little bit of crookedness in the mind will later turn into a major warp. Reflect on this.

Do not sleep under a roof. Carry no money or food. Go alone to places frightening to the common brand of men. Become a criminal of purpose. Be put in jail, and extricate yourself by your own wisdom.

You may abandon your own body but you must preserve your honour.

Develop intuitive judgement and understanding for everything.

If the enemy thinks of the mountains, attack like the sea; and if he thinks of the sea, attack like the mountains.

When you attack the enemy, your spirit must go to the extent of pulling the stakes out of a wall and using them as spears and halberds.

Cutting down the enemy is the way of strategy, and there is no need for many refinements of it.
