The technique of the Aikido is organized around a circular movement, since all conflict is solved through the spirit of the circle. For that reason, the reaction from body and mind and the principle of the circle creation are vital for the Aikido techniques. A circle delimits a certain space and Ki is born from the perfect freedom of the emptiness therefore created. The creative processes of life are united by action of the spirit, to the infinite universe from the center of the circle. The spirit is the creator, the eternal father from whom all the things are born.

By virtue of this principle, the creative process of the spirit is limited. Within this circle, the Ki of the universe becomes jumbled in the process of evolution and protection. The movement of the Karma registers in the circle of the balance and the budo of the Aikido registers itself into the circle of the protection. The circle of the spirit is the spring of the Ki, it unites the spirit to the matter through Aikido. This one contains and creates innumerable techniques because it locks up all the Ki of the universe. Without the glory and wisdom, integrity could not exist, nor the possibility of uniting the spirit and matter. Even worse, the functions of recovery of the organism wouldn’t exist. That is constant Kokyu’s circle renovation.

The circle of spirit begins and finishes in the unit of the universe. The Budo of Aikido emerges from the dominion of this spirit. The essence of this Budo is to include the reaction of cause and effect, as well as to approach each thing as if one had taken it by the hand. Everyone has a spirit and must be conscientious of the spirit that each human being has. Everything is solved through the principle of the circle. And the secret of the circle is to create a technique that penetrates in the heart of space.
