Aikido, as Ueshiba conceived it in his mature years, is not primarily a system of combat, but rather a means of self-cultivation and improvement. Aikido has no tournaments, competitions, contests, or "sparring." Instead, all aikido techniques are learned cooperatively at a pace commensurate with the abilities of each trainee. According to the founder, the goal of aikido is not the defeat of others, but the defeat of the negative characteristics which inhabit one's own mind and inhibit its functioning.

At the same time, the potential of aikido as a means of self-defense should not be ignored. One reason for the prohibition of competition in aikido is that many aikido techniques would have to be excluded because of their potential to cause serious injury. By training cooperatively, even potentially lethal techniques can be practiced without substantial risk.

It must be emphasized that there are no shortcuts to proficiency in aikido (or in anything else, for that matter). Consequently, attaining proficiency in aikido is simply a matter of sustained and dedicated training. No one becomes an expert in just a few months or years.

Aikido's founder, Morihei Ueshiba, was born in Japan on December 14, 1883. According to the founder's son, Kisshomaru, when Morihei was a boy, he saw local thugs beat up his father for political reasons. He set out to make himself strong so that he could take revenge. He devoted himself to hard physical conditioning and eventually to the practice of martial arts, receiving certificates of mastery in several styles of jujitsu. In spite of his impressive physical and martial capabilities, however, he felt very dissatisfied. He began delving into religions in hopes of finding a deeper significance to life, all the while continuing to pursue his studies of budo, or the martial arts. By combining his martial training with his religious and political ideologies, he created the modern martial art of aikido. Ueshiba decided on the name "aikido" in 1942 (before that he called his martial art "aikibudo"and "aikinomichi").

On the technical side, aikido is rooted in several styles of jujitsu (from which modern judo is also derived), in particular daitoryu-(aiki)jujitsu, as well as sword and (possibly) spear fighting arts. Oversimplifying somewhat, we may say that aikido takes the joint locks and throws from jujitsu and combines them with the body movements of sword and spear fighting. However, it may be that many aikido techniques were the result of the founder's own innovation.

On the religious side, Ueshiba was a devotee of one of Japan's so-called "new religions," Omotokyo. Omotokyo was (and is) part neo-Shintoism, and part socio-political idealism. One goal of Omotokyo has been the unification of all humanity in a single "heavenly kingdom on earth" where all religions would be united under the banner of Omotokyo. It is impossible sufficiently to understand many of O- sensei's writings and sayings without keeping the influence of Omotokyo firmly in mind. Despite what many people think or claim, there is no unified philosophy of aikido. What there is, instead, is a disorganized and only partially coherent collection of religious, ethical, and metaphysical beliefs which are only more or less shared by aikidoka, and which are either transmitted by word of mouth or found in scattered publications about aikido.
