The etheric body has been described as a network, permeated with fire, or as a web, animated with golden light. It is spoken of in the Bible as the "golden bowl." [80] It is a composition of that matter of the physical plane which we call etheric, and its shape is brought about by the fine interlacing strands of this matter being built by the action of the lesser Builders into the form or mould upon which later the dense physical body can be molded. Under the Law of Attraction, the denser matter of the physical plane is made to cohere to this vitalized form, and is gradually built up around it, and within it, until the interpenetrating is so complete that the two forms make but one unit; the pranic emanations of the etheric body itself play upon the dense physical body in the same manner as the pranic emanations of the sun play upon the etheric body. It is all one vast system of transmission and of interdependence within the system. All receive in order to give, and to pass on to that which is lesser or not so evolved. Upon every plane this process can be seen.
Thus the etheric body forms the archetypal plane in relation to the dense physical body. The thinker on his own plane stands, in relation to the physical, as the Logos to His system. In the synthesis of thought it might be expressed thus: The thinker on the astral plane, the plane of desire and of necessity, stands to the physical body as the Logos on the cosmic astral plane stands to His system.
