Book excerpt: The Holy Grail is many things to many people. The medieval troubadour saw it as a vision of heaven. In the twenty-first century, the quantum physicist finds heaven in parallel universes. The shaman, who links prehistory with the modern world, travels in other dimensions knowing he will experience the parameters of existence. In "Sun God and Moon Maiden," Gordon Strong suggests that the presence of the Grail questions not only space and time but perception itself. The philosophy of Plato, the psychology of Jung and the nobility of kings are within the Grail's domain. It resides in the endless galaxy of the mind. This interior landscape is where we discover yet more gateways into Inner Space, realms where we may come to know the universe, and ourselves. From Atlantis to Arthur's Camelot, the path to Avalon still awaits. As Gordon Strong demonstrates in this fascinating book - encompassing mythology, magic and modern physics - the ancient wisdom of the Qabalah, the Tarot and Sacred Stone Circles are poised to lead us to the Chalice of Inspiration.
