The movement of Aikido is the dynamic movement of the universal energy force. The power of Aikido is the power of a strong and unified spirit, mind and body moving in harmony with everything around it. Its origin is Budo. Its development is the result of two thousand years of a cultural process of change and refinement, a continuing martial contest of natural selection. It is an evolution etched in blood.

The study of Budo and the development of Aikido was the life work of Morihei Ueshiba, a figure of great renown who traveled the length and breadth of Japan studying under the greatest masters of many arts. Hard work, severe discipline and all the money he could earn were poured into his mastery of the sword, the spear and the arts of self defense. Deeply interested in the study of spiritual thought, he had also practiced many different spiritual disciplines. Yet he was unable to unite his spiritual beliefs with his physical accomplishments.

A short time after returning from military action in the Russo-Japanese War, he retired to a small house located on a mountain outside his village. There he lived and studied silently; his days spent training his body and his nights spent deep in prayer. It was at the end of this time of severe training that he had the realization he had been seeking all his life. At that moment nature's process became clear and he knew that the source of Budo is the spirit of protection of all things.

"Budo is not felling the opponent by force; nor is it a tool to lead the world into destruction by 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."

Morihei Ueshiba intimately recognized and understood the harmony and power of the creative process from which all things evolve. His art was the sword, his creative way was Budo. His understanding and enlightenment is creatively expressed by the protection of all life through a powerful and graphic application of universal truth. Aikido is creation, not destruction. It is a positive energy which creates harmony and justice out of violence.

To talk of harmony and justice is simple. But to apply those principles to the conflicts which we face everyday requires a deep understanding and sincere trust. Logic may tell us that truth lies within the process of harmony, but the moment something of value rests on the outcome of a situation we no longer trust that logic. The beautiful ideas and eloquent phrases are forgotten under the pressures of reality. In philosophy a theory of truth is expressed in words, but the truth of Aikido is expressed in action, the theory proven in practice. By the physical application of its principles we develop a deeper understanding in the heart instead of the mind. Through practice and experience we learn to trust its power.

Aikido training is to challenge yourself, not the other. You will develop confidence by facing your fears, and negative fighting spirit will become creative fighting spirit. The stress and pressure of serious Aikido training brings this spirit to the surface, exposing it so that it can be examined and refined in a controlled atmosphere of respect and mutual study.
