THE BODY SHOULD be triangular, the mind circular. The triangle represents the generation of energy and is the most stable physical posture. The circle symbolizes serenity and perfection, the source of unlimited techniques. The square stands for solidity, the basis of applied control.
Morihei UeshibaA mind to serve for the peace of all human beings in the world is needed in Aikido, and not the mind of one who wishes to be strong or who practices only to fell an opponent.
