One simple apology is enough. Get up and don’t do it again - Morihei Ueshiba

When you lose your desire for things that do not matter, you will be free.

The heart of a human being is no different from the soul of heaven and earth. In your practice always keep in your thoughts the interaction of heaven and earth, water and fire, yin and yang.

The Art of Peace is the principle of nonresistance. Because it is nonresistant, it is victorious from the beginning. Those with evil intentions or contentious thoughts are instantly vanquished. The Art of Peace is invincible because it contends with nothing.
