(Q) "Do the aurascopic pictures which I hold in my hand represent actual conditions on the dates given?"
(A) "Not as we find. If viewed from the actual emanations through the auras of the body itself (not aura, but auras), they would be quite different!
To gain the proper aura from a mechanical manner, prepare an aurascope like this:
Make prisms, or combined prisms - see? Jena [Encyclopedia Britannica cc 1957: JENA, a university town of Germany... seat of the famous Zeiss firm of optical instrument makers] glass for the white one, lapis for the blue one, the blood ruby for the red one, the yellow lapis for the yellow one. Combine these on a spindle, so that each may be turned through an opening that is directed towards a body. With the second turn there will come into vision, for anyone of any psychic ability, the direct aura - physical AND spiritual - for anyone at whom it is pointed.
In making the diagnosis, it would require the nude body; and those portions of the body affected will show the various tints or forms of depressions, ranging from all colors that are negative in their action to life - which are leaden and various shades of purple, and the orange that turns towards red. These prisms would be set. They would be of these dimensions: From a quarter (1/4 inch on the thin edge to a three-quarter (3/4) on the heavy edge. An inch (1") wide and two inches (2) long. Necessarily two sets would be prepared, so that there may be the vision from both eyes - for in few people is vision exactly the same in both eyes; but these would be so set that they would be turned on an axis, an inch to two inches (1" to 2") apart, see? so they would turn around, see?"
(Q) "Would the axis be through the center?"
(A) "The axis would be that the prisms would be set in a holder on the axis. Of course, do not attempt to bore through the prisms themselves - but these are set in holders, see, in something like the leaves of a willowing fan."
(Q) "What is the distance from the eyes to the prisms?"
(A) "Nine inches (9")."
(Q) "Are any other lenses necessary?"
(A) "Naturally the plain glass in the end of the scope, and turned - you see - or set on axis so that the vision comes as one; as when looking through the scope that makes for the projection of flat object as to give them the perspective value to the whole, see?"
