Aikido principles

Ueshiba created the principle of non resistance, a violence-free path of self defence. By coordinating his or her movements with the movements of another person, he or she can learn to adopt the movements of the other person as his or her own, to control it and thus neutralize the attack.
Through this, harmony is re-introduced and peace can prevail. Ueshiba only did what was necessary to control the attacker, with causing minimum bodily harm
