Paul Marshall invites us to embark on a supreme adventure of self-knowledge. He articulates a vision of the potential self we all are, a vision of ourselves transformed, in harmony with each other and, crucially, with the natural world. Highly recommended.

In this remarkable book, Marshall persuasively enchants us with the recognition that we are not a world of separate selves but are all intimately interconnected in a cosmic unity that is our divine self.

“Materialism” in its philosophic and socioeconomic guises threatens the very survival of modern civilization, and we desperately need an enlarged conception of nature that can overcome the contemporary alienation between science and spirituality. In this beautifully written book Paul Marshall addresses that need by bringing to bear both an uncommon knowledge of the world’s religious and mystical traditions, directly informed by mystical experiences of his own, and a deep understanding of relevant developments in modern physics. An outstanding contribution.
