The first achievement in the art of sword fighting is unity of man and sword. When this unity is achieved, even a blade of grass can be a weapon.
The second achievement is that the sword exists only in the heart of the master, being absent in his hand. Then it is possible to hit the enemy in a hundred paces with the bare hands.
But the supreme achievement of art of sword fighting is the lack of a sword in hand and in the heart of the master. This warrior is in peace with the world. He makes a vow not to kill and brings peace to mankind.
The whole secret of existence is to have no fear.
Having been born into the house of a warrior, one's intentions should be to grasp the long and the short swords and to die.
