Augoeides

Augoeides is a Greek term meaning "luminous body" (from auge "bright light, radiance" + eidos "form, shape") used by Neoplatonists and later by Bulwer-Lytton in Zanoni.

H. P. Blavatsky writes:

Bulwer Lytton calls it the “Luminous Self”, or our Higher Ego. But Occultism makes of it something distinct from this. It is a mystery. The Augoeides is the luminous divine radiation of the EGO which, when incarnated, is but its shadow-pure as it is yet. This is explained in the Amshaspends and their Ferouers.

The seventh aspect of this individual aura is the faculty of assuming the form of its body and becoming the “Radiant,” the Luminous Augoeides. It is this, strictly speaking, which at times becomes the form called Mâyâvi-Rûpa.
