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 UeshibaNonresistance is one of the principles of aikido. Because there is no resistance, you have won before even starting. People whose minds are evil or who enjoy fighting are defeated without a fight.
