Many people regard Buddhism as a religion, but if we say that it is a way of life, we may be closer to the truth.
Life is the art of bringing happiness to others and ourselves. If we ourselves are not happy, we cannot make others happy, and if others are not happy, we cannot be truly happy either.
To practice the art of bringing happiness to ourselves and others, we need to have faith and confidence in something that we find true and beautiful, that accords with the truth, and that can be a foundation for true and lasting happiness.
Because we need such faith, Buddhism is also called a religion.
Faith here does not mean faith in a creator god or a metaphysical first principle, the existence of something of which we cannot really prove.
Faith here means confidence in something beautiful and true that can bring about happiness and that we can actually touch.
-Thich Nhat Hahn
