The "outer light" by which the physical eye is able to see objects is sunlight. Upon this clairvoyant vision in no wise depends, involving, as it does, other octaves of vibration. We should be able to receive ideas of this order without incredulity since the advent of "dark" photography and the ultra-violet microscope. By aid of the latter, photographs are taken in absolute darkness, the lenses used being transparent to light rays invisible to the eye, but active photographically.
The foregoing passages from The Virgin of the World show a remarkable resemblance between the Hermetic philosophy and modern higher-space thought. The parallelism is not less striking in the case of certain other mystic philosophers of the East.
PLATO'S SHADOW-WATCHERS
"Parmenides," says Hinton, "and the Asiatic thinkers with whom he is in close affinity, propound a theory of existence which is in close accord with a conception of a possible relation between a higher and a lower-dimensional space." He concludes, "Either one of two things must be true, that four-dimensional conceptions give a wonderful power of representing the thought of the East, or that the thinkers of the East must have been looking at and regarding four-dimensional existence."
