This capacity of waking up, of being aware of what is going on in your feelings, in your body, in your perceptions, in the world, is called Buddha nature, the capacity of understanding and loving. Smiling is very important. If we are not able to smile, then the world will not have peace. It is not by going out for a demonstration against nuclear missiles that we can bring about peace. It is with our capacity of smiling, breathing, and being peace that we can make peace.

— Thich Nhat Hanh
