“In order to establish heaven on earth, we need a Budo that is pure in spirit, that is devoid of hatred and greed.”
The Art of Peace (1992)
Context: 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.

Letter published in The Tribune (25 December 1929), with some reference to lines from Idylls of the King by Alfred Tennyson
Context: Revolution did not necessarily involve sanguinary strife. It was not a cult of bomb and pistol. They may sometimes be mere means for its achievement. No doubt they play a prominent part in some movements, but they do not — for that very reason — become one and the same thing. A rebellion is not a revolution. It may ultimately lead to that end.
The sense in which the word Revolution is used in that phrase, is the spirit, the longing for a change for the better. The people generally get accustomed to the established order of things and begin to tremble at the very idea of a change. It is this lethargical spirit that needs be replaced by the revolutionary spirit. Otherwise degeneration gains the upper hand and the whole humanity is led stray by the reactionary forces. Such a state of affairs leads to stagnation and paralysis in human progress. The spirit of Revolution should always permeate the soul of humanity, so that the reactionary forces may not accumulate to check its eternal onward march. Old order should change, always and ever, yielding place to new, so that one “good” order may not corrupt the world. It is in this sense that we raise the shout “Long Live Revolution.”

An account of an experience of transcendent awareness, soon after a contest where, unarmed, he defeated a naval officer armed with a bokken (wooden sword) without harming him; as quoted in Aikido (1985) by Kisshomaru Ueshiba <!-- Hozansha Publications, Tokyo -->
Context: I felt the universe suddenly quake, and that a golden spirit sprang up from the ground, veiled my body, and changed my body into a golden one. At the same time my body became light. I was able to understand the whispering of the birds, and was clearly aware of the mind of God, the creator of the universe.
At that moment I was enlightened: the source of Budo is God's love — the spirit of loving protection for all beings … Budo is not the felling of an opponent by force; nor is it a tool to lead the world to destruction with arms. True Budo is to accept the spirit of the universe, keep the peace of the world, correctly produce, protect and cultivate all beings in nature.
