Hanh Nhat Thich, The Heart of the Buddha's Teaching: Transforming Suffering into Peace, Joy, and Liberation

"Letting go gives us freedom, and freedom is the only condition for happiness. If, in our heart, we still cling to anything - anger, anxiety, or possessions - we cannot be free."

"The seed of suffering in you may be strong, but don't wait until you have no more suffering before allowing yourself to be happy."
