The source of peace is within us; so also the source of war. And the real enemy is within us, and not outside. The source of war is not the existence of nuclear weapons or other arms. It is the minds of human beings who decide to push the button and to use those arms out of hatred, anger or greed.
Dalai LamaIf you have only education and knowledge and a lack of the other side, then you may not be a happy person, but a person of mental unrest, of frustration. Not only that, but if you combine these two, your whole life will be a constructive and happy life. And certainly you can make immense benefit for society and the betterment of humanity. That is one of my fundamental beliefs: that a good heart, a warm heart, a compassionate heart, is still teachable.
Dalai Lama
