"Extraordinary patience is necessary to work toward world peace, and the source of that patience is inner peace. Such peace enables us to see clearly that war and suffering are outer reflections of the mind's poisons. The essential difference between peacemakers and those who wage war is that peacemakers have discipline and control over egotistical anger, grasping, jealousy, and pride, whereas warmakers, out of ignorance, cause these poisons to manifest in the world. If you truly understand this, you will never allow yourself to be defeated from within or without."
Chagdud Rinpoche
