"There is no enemy in Aikido. It is wrong to think that having an opponent or an enemy, or trying to be stronger than him and trying to overpower him is true budo.
True Budo has no opponent, true Budo has no enemy. True Budo is to become one with the Universe. The purpose of Aikido practice is not to become strong, nor is it to fell an opponent. Rather, it is necessary to have one's heart at the center of the universe, then as little as it may be, help maintain peace among the peoples of the earth.
Aikido is both like a compass that enables each person to realize his own individual destiny, as well as a way of unity and love. At anywhere, at anytime, no matter how anyone may attack me, I have no fear, for I have left everything in the hands of God. This is not just when holding a sword, but always; for one must have a heart that clings neither to life nor death, but rather one that leaves things in the hands of the Creator.
Aiki is not a technique to fight with or defeat the enemy. It is the way to reconcile the world and make human beings one family." (O-Sensei)
