Eckhart Tolle is a German spiritual teacher. At 29 he went through a major inner transformation in his life, at that point he devoted the next few years of his life to understanding.
“Who you are is not what you did…Be the awareness not the conditioned pattern.”
His book, “A New Earth” discusses the egoic state and pain body and how to identify yourself as separate from it. He advises us “how” to wake up, and recognize awareness.
