14 : Fudoshin
Ki Sayings (2003)
Context: True "fudoshin" is not a rigid, immobile state of mind, but the condition of stability, which comes from the most rapid movement. In other words, like the steadiness of a spinning top, the state of perfect spiritual and physical stability arises from movement, which continues infinitely and is so infinitely rapid that it is imperceptible.

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.
