"If 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."
