The first priority to the ninja is to win without fighting.

Your life is on the line, practice well.

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.

Always be able to kill your students

Those who desire only techniques will never understand this art. It is everything beyond that

If you do not let go of thinking about forms, you will not understand what I am showing.
