What is the nature of the mind? How does it act as a lens for the spirit? Does the material body limit the power of the soul? Is intuition a type of clairvoyance? How can we hone the enormous innate potential of the human brain? This guide to the study of the paranormal perception we can all tap into-first published in 1911-offers philosophical exploration and practical advice for honing your extrasensory insight. From the best diet to consume to the most advantageous compass direction to sit facing while meditating to a surprising "valuable accessory" that will help "bring about the necessary receptivity," this is a profound and poetic appraisal of cerebral and psychic potency, complete with experiments anyone can conduct to develop and refine the clairvoyant capabilities. JESSE CHARLES FREMONT GRUMBINE is author of numerous books on the paranormal and spirituality, including Evolution and Christianity (1887), Immortality (1899), Auras and Colors (1900), and Proof of Spirit Identity and Guidance (1909).
