Thich Nhat Hanh said this quote

Look deeply at your anger, as you would look at your own child. Don’t reject it or hate it. The point of meditation is not to turn yourself into a battlefield, one side opposing the other. Conscious breathing soothes and calms the anger, and mindfulness penetrates it. Anger is just an energy, and all energies can be transformed. Meditation is the art of using one kind of energy to transform another.
