In neo-Theosophy, the etheric body, ether-body, or æther body is the subtle body propounded in esoteric philosophies as the first or lowest layer in the human energy field or aura]
The etheric body is said to be in immediate contact with the physical body and to sustain it and connect it with "higher" bodies.
It is also said to consist of a finer substance, more pure, and composed of smaller particles, than the ordinary matter of the physical plane.
The term gained some general popularity after the 1914-1918 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.
In popular use it is often confounded with the related concept of the astral body as for example in the term astral projection - the early Theosophists had called it the "astral double".
Others prefer to speak of the "lower and higher astral".
