By being able to see things from different angles, and indeed, realms, clairvoyant mediums can provide insight that you might not be able to perceive yourself. What makes clairvoyant readings extraordinary is that the clairvoyant psychic is able to connect you to memories, events, emotions, and predictions that would remain inaccessible to you otherwise. In other words, clairvoyant mediums provide a bridge between you and the spiritual realm – whether it’s your own subconscious knowledge, the greater collective unconscious, angels, spirit guides, or the powerful energies all around you.
In 1880 the American stage mentalist Washington Irving Bishop published a book revealing how mediums would use secret codes as the trick for their clairvoyant readings. The Seybert Commission was a group of faculty at the University of Pennsylvania who in 1884–1887 exposed fraudulent mediums such as Pierre L. O. A. Keeler and Henry Slade. The Fox sisters confessed to fraud in 1888. Margaret Fox revealed that she and her sister had produced the "spirit" rappings by cracking their toe joints.
