"A Course in Miracles" is part of a long intellectual tradition that includes illustrious people such as the German philosopher Friedrich Nietzsche. Among the important works he authored, "On the Three Metamorphoses," from his masterpiece "Thus Spoke Zarathustra," provides the framework for this discussion of the stages of our spirituality. Using Nietzsche's parable of the camel, lion, and child, this book unfolds the process of spiritual development woven into the teachings of the Course. As these teachings demonstrate, the process is essentially a journey that proceeds in and through the world and on to spiritual maturity, this final stage marked by the ease of being in the world but not of it, seeing everything through the eyes of forgiveness.
