The etheric body, ether-body, æther body, a name given by neo-Theosophy to a vital body or subtle body propounded in esoteric philosophies as the first or lowest layer in the "human energy field" or aura. It is said to be in immediate contact with the physical body, to sustain it and connect it with "higher" bodies.
The English term "etheric" in this context seems to derive from the Theosophical writings of Madame Blavatsky, but its use was formalised by C.W. Leadbeater and Annie Besant due to the elimination of Hindu terminology from the system of seven planes and bodies.
The term gained some general popularity after the 1914-18 war, Walter John Kilner having adopted it for a layer of the "human atmosphere" which, as he claimed in a popular book, could be rendered visible to the naked eye by means of certain exercises.
The classical element Aether of Platonic and Aristotlean physics continued in Victorian scientific proposals of a Luminiferous ether as well as the cognate chemical substance ether. According to Theosophists and Alice Bailey the etheric body inhabits an etheric plane which corresponds to the four higher subplanes of the physical plane.
