“The absolute universe is one. We call this ki.”
3 : The way to union with ki
Ki Sayings (2003)
Context: The absolute universe is one. We call this ki. Our lives and our bodies are born of the ki of the universe. Study thoroughly the principles of the universe and practice them. We are one with the universe. There is no need to despond, no need to fear. The way we follow is the way of the universe, which no difficulty nor hard-ship can hinder. Let us have the courage and say, "if I have a clear conscience and a calm spirit, I dare to face an enemy of ten million."

Context: !-- We would cease to exist if removed from the laws of nature. For instance, we would be totally unable to maintain stability on the surface of the earth without the force of gravity. --> Only those with their eyes open to the world of nature are capable of uncovering its truth. Everything springs from a sense of gratitude toward nature. Aikido, though praised as a healthful system of self-defense techniques, would be nothing apart from the laws of the great universe. The martial way begins and ends with courtesy, itself an attitude of thankfulness to and reverence for nature. To be mistaken on this basic point is to make of the martial arts no more than weapons of injury and death.
The very name Aikido indicates its dependence on the laws of nature, which we term ki. Aikido means the way to harmony with ki. That is to say, Aikido is a discipline to make the heart of nature our own heart, to understand love for all things, and to become one with nature. Techniques and physical strength have limits; the great way of the universe stretches to infinity.
