Thich Nhat Hanh

Although attempting to bring about world peace through the internal transformation of individuals is difficult, it is the only way. Wherever I go, I express this, and I am encouraged that people from many different walks of life receive it well. Peace must first be developed within an individual. And I believe that love, compassion, and altruism are the fundamental basis for peace. Once these qualities are developed within an individual, he or she is then able to create an atmosphere of peace and harmony. This atmosphere can be expanded and extended from the individual to his family, from the family to the community and eventually to the whole world.
