In Clairvoyance, J. C. F. Grumbine presents a structured exploration of the theory, practice, and spiritual significance of clairvoyant perception. Written in the early 20th century as part of his "e;College of Divine Sciences,"e; Grumbine's book outlines the development of extrasensory faculties, offering both philosophical context and practical exercises. He emphasizes the law-like nature of spiritual gifts and insists that clairvoyance is not mere fortune-telling, but a disciplined awakening of the soul's latent powers. The book blends mysticism, metaphysical idealism, and early New Thought, positioning clairvoyance as a legitimate path to higher knowledge and spiritual realization. Ideal for those curious about occult practice or psychic development.
