Move with your feet, the hands will follow.

There was a famous Zen master whom people would seek out to become enlightened. He was strict and would occupy people with things having nothing to do with seeking enlightenment. You see, that is the only way to achieve enlightenment; by not focusing on achieving it. Then, one day it will just come to you.

Always be able to kill your students

Nature is your friend; it helps you to win. Your enemy will have unnatural movement, therefore you will be able to know what he is going to do before he does it.

Learning a technique is not an end in itself, it merely indicates where you need to start.

Focus on the future for 50%, on the present for 40%, and on the past for 10%

Any place we can breathe, we can do Ninjutsu.
