The memorized images of interest to an individual that make up a particular aspect of his astral resources. Each image is an "icon" (or thought form) that contains emotions as well as facts, historical reality as well as fantasies, actual stories and imagined ones, etc. The original photographs and illustrations themselves are “auric signatures” that include etheric and astral energies derived from all that has ever occurred to the place, thing or person photographed, and that will happen.
