Strategy is the craft of the warrior.
Consider yourself lightly; consider the world deeply.
You may abandon your own body but you must preserve your honour.
Determine that today you will overcome your self of the day before, tomorrow you will win over those of lesser skill, and later you will win over those of greater skill.
To become the enemy, see yourself as the enemy of the enemy
It is difficult to realize the true Way just through sword-fencing. Know the smallest things and the biggest things, the shallowest things and the deepest things.
