Studies in the Out-Lying Fields of Psychic Science

Studies in the Out-Lying Fields of Psychic Science is a classic spiritual studies text by Hudson Tuttle. There is a Psychic Ether, related to thought, as the luminiferous ether is to light. This may be regarded as the thought atmosphere of the universe. A thinking being in this atmosphere is a pulsating center of thought-waves, as a luminous body is of light. There is a state of mind and body known as sensitive, or impressible, in which it receives impressions from other minds. This state may be normal, or induced by fatigue, disease, drugs, or arise in sleep. The facts of clairvoyance, trance, somnambulism and psychometry prove the existence of this ether, and are correlated to it.
