“As a physicist who has taught at the university level, Poncelet incorporates his knowledge of cosmology, nuclear physics, and astrophysics into his explanations of shamanic principles. Among other things, he ties Einstein's theories of relativity to ancient spiritual beliefs about the malleability of time, Heisenberg's uncertainty principle to the traditional mystical concept of the Void, and the discoveries of quantum physics to the principles of nonduality and interconnectedness.” —Spirituality and Health

“The Shaman Within affirms how we each possess the natural ability to experience our interconnected wholeness with all of nature, even as we engage in our everyday lives and the technological activities of this modern world, which too often keep us feeling separate and isolated behind the screens of our computers and smartphones. Poncelet shows us the way.” —Richard Miller, PhD, author of Yoga Nidra

Johnson, author of The Sacred Yes and Your Deepest Intent
