The etheric body, also known as ether-body or æther body, a name given by neo-Theosophy to a vital body or subtle body put forward 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 in the (Adyar School of Theosophy).
Linga sarira is a Sanskrit term for the invisible double of the human body, the etheric body or etheric double (or astral body as it is known in some Theosophical concepts). It is one of the seven principles of the human being, according to Theosophical philosophy. Narrated and Created by A.Christie (Ancient Mystery)
