"Techniques employ four qualities that reflect the nature of our world. Depending on the circumstance, you should be: hard as a diamond, flexible as a willow, smooth-flowing like water, or as empty as space."

“True Budo is done for the sake of "building peace". Train every day so as to make peace between this spirit and all things manifested on the face of the Earth.”

“As your Bujutsu training approaches perfection you will be able to detect the suki , even before he can, and as if to satisfy some deficiency in him, you can fill the suki with your technique.”

“The Way of the Warrior has been misunderstood. It is not a means to kill and destroy others. Those who seek to compete and better one another are making a terrible mistake. To smash, injure, or destroy is the worst thing a human being can do. The real Way of a Warrior is to prevent such slaughter — it is the Art of Peace, the power of love.”

“In the Art of Peace we never attack. An attack is proof that one is out of control. Never run away from any kind of challenge, but do not try to suppress or control an opponent unnaturally. Let attackers come any way they like and then blend with them. Never chase after opponents. Redirect each attack and get firmly behind it.”

“In order to establish heaven on earth, we need a Budo that is pure in spirit, that is devoid of hatred and greed. It must follow natural principles and harmonize the material with the spiritual. Aikido means not to kill. Although nearly all creeds have a commandment against taking life, most of them justify killing for reason or another. In Aikido, however, we try to completely avoid killing, even the most evil person.”

“Shihonage is the foundation of Aikido. All you ever need to master is shihonage.”
