Astral projection

Astral projection (or astral travel) is a term used in esotericism to describe a willful out-of-body experience (OBE), a supposed form of telepathy, that assumes the existence of a soul or consciousness called an "astral body" that is separate from the physical body and capable of travelling outside of it throughout the universe.

The idea of astral travel is rooted in esotericism and occultism, and was promoted by 19th century Theosophists—philosophers who explored the mystical and preternatural origins of the natural world. It is sometimes reported in association with dreams, and forms of meditation. Some individuals have reported perceptions similar to descriptions of astral projection that were induced through various hallucinogenic and hypnotic means (including self-hypnosis). There is no scientific evidence that there is a consciousness or soul which is separate from normal neural activity or that one can consciously leave the body and make observations. Claims of scientific evidence of astral projection are pseudoscientific.

According to classical, medieval and renaissance Hermeticism, Neoplatonism, and later Theosophist and Rosicrucian thought the astral body is an intermediate body of light linking the rational soul to the physical body while the astral plane is an intermediate world of light between Heaven and Earth, composed of the spheres of the planets and stars. These astral spheres were held to be populated by angels, demons and spirits.

The subtle bodies, and their associated planes of existence, form an essential part of the esoteric systems that deal with astral phenomena. In the neo-platonism of Plotinus, for example, the individual is a microcosm ("small world") of the universe (the macrocosm or "great world"). "The rational soul...is akin to the great Soul of the World" while "the material universe, like the body, is made as a faded image of the Intelligible". Each succeeding plane of manifestation is causal to the next, a world-view called emanationism; "from the One proceeds Intellect, from Intellect Soul, and from Soul - in its lower phase, or that of Nature - the material universe".
