Never depart from the way of martial arts.

from one thing, know ten thousand things

Do not let the body be dragged along by mind nor the mind be dragged along by the body

By knowing things that exist, you can know that which does not exist.

In time, all things work to your advantage when you pursue them with an open heart.
