In the words of O'Sensei
"Budo is not a matter of physical strength, the handling of weapons with great skill,
nor the ability to strike another person down before he can do the same to you.
It is the path toward eternal wisdom and spiritual understanding.
Nevertheless, if it is not effective in actual practice, it loses its spiritual value and uniqueness as well.
In true budo, there is no enemy.
You shouldn't train to become strong or to be able to defeat an enemy but rather that you can be of use to world peace."
