Aikido training teaches one to contain impulsive reactions to provocations.
Typically the Limbic system will cause a reaction to freeze, fight or flee, and this happens in conversation and well as physical actions. The reaction is rarely appropriate and the response often disproportionate.
Aikido training gives more mindful measured responses. [Principles of Aikido]
A highly ethical response develops which diffuses an attack through compassion and beneficent intention. Ultimately, an attacker would see no gain or advantage in proceeding.
The founder advocates Aikido as the way of living in harmony with everything. It is an embodiment of selfless love.
