This little book clearly explains this law of manifestation but then takes it a quantum leap further, revealing how to create what is truly important in life — happiness, fulfillment, inner peace, and making the world a better place for all. “Marc’s unique approach to success and fulfillment is inspiring and surprisingly practical.” — Shakti Gawain “ The Greatest Secret of All is a wonderful contribution to humanity.
