Dalai Lama said this quote

Our lives are in constant flux, which generates many predicaments. But when these are faced with a calm and clear mind supported by spiritual practice, they can all be successfully resolved. When our minds are clouded by hatred, selfishness, jealousy, and anger, we lose not only control but also our judgment. At those wild moments, anything can happen, including war. Although the practice of compassion and wisdom is useful to us all, it is especially valuable for those responsible for running national affairs, in whose hands lie the power and opportunity to create a framework for world peace.
