One of the most helpful books I've read during my journey of recovery is The Heart of Buddha's Teaching; Transforming Suffering into Peace, Joy, and Liberation
by Thich Nhat Hanh. The author shares comforting wisdom about the nature of suffering and it's role in creating compassion, love, and joy - all qualities of enlightenment. My favorite quote from the book:
"To transform suffering, your heart must be as big as the ocean."
