If you face the tree with no intention and do not fix your eyes on a single leaf, then you will see all the many leaves.

“There may be a hundred stances and sword positions, but you win with just one.”

“See first with your mind, then with your eyes, and finally with your body.”

“When you strike a blow, do not let your mind dally on it, not concerning yourself with whether or not it is a telling blow; you should strike again and again, over and over, even four or five times. The thing is not to let your opponent even raise his head.”
