Opportunistic relationships can hardly be kept constant. The acquaintance of honorable people, even at a distance, does not add flowers in times of warmth and does not change its leaves in times of cold: it continues unfading through the four seasons, becomes increasingly stable as it passes through ease and danger.

Battles are not won by strength alone!

Those who are skilled in combat do notbecome angered, those who are skilled at winning do not become afraid. Thus the wise win before they fight, while the ignorant fight to win.

The loss of any army is always caused by underestimating the enemy. Therefore gather information and watch the enemy carefully.

Nothing is harder to see into thanpeoples nature. The sage looks at subtle phenomena and listens tosmall voices. This harmonizes the outside with the inside and the inside with the outside.

There is no greater weapon than a prepared mind.

What loss is there in dignity, what worry is there of failure?
