Morihei Ueshiba, O’Sensei

Aikido was developed by Morihei Ueshiba (1883-1969), known to Aikido students as O Sensei (Great Teacher).As a young man, he overcame debilitating childhood illnesses through martial arts practice, eventually becoming a master of the sword, the staff, the spear, and the art of ju-jitsu.

O Sensei also held strong Shinto religious convictions concerning the ultimate futility of conflict and the illusory character of victory based on strength. This internal contradiction, which drove O Sensei to adopt a life of austerity and rigorous training, was resolved through an enlightenment experience which led to the development of Aikido, a martial art influenced by a philosophy of universal harmony.
