Do not regret what you have done

Aspire to be like Mt. Fuji, with such a broad and solid foundation that the strongest earthquake cannot move you, and so tall that the greatest enterprises of common men seem insignificant from your lofty perspective. With your mind as high as Mt Fuji you can see all things clearly. And you can see all the forces that shape events; not just the things happening near to you.

The important thing in strategy is to suppress the enemy's useful actions but allow his useless actions

As if with the nut and flower, the nut has become less than the flower... both those teaching and those learning are concerned with colouring and showing off their technique, trying to hasten the bloom of the flower.

This is truth: When you sacrifice your life, you must make fullest use of your weaponry. It is false not to do so, and to die with a weapon as yet undrawn.

When you decide to attack, keep calm and dash in quickly, forestalling the enemy...attack with a feeling of constantly crushing the enemy, from first to last.

Study strategy over the years and achieve the spirit of the warrior. Today is victory over yourself of yesterday; tomorrow is your victory over lesser men.
