Genuine Mediumship; or, The Invisible Powers

The book presents an account of mediumship and psychic phenomena framed as natural extensions of vibratory and etheric forces, proposing that mental energy can be transmitted, received, and transformed across interpenetrating planes. It explains concepts such as mental vibrations, telepathic transmission, clairvoyance, automatic writing, and the possible physiological role of organs like the pineal gland, and differentiates benign and harmful uses of psychic power. Practical instruction and experimental methods for developing sensitivity, testing claims, and guarding against adverse influences are provided alongside arguments that occult phenomena merit rational, scientific consideration rather than dismissal.
