Nothing that takes place, no manifestation however rapid or weak, can ever be lost from the Skandhic record of a man's life. Not the smallest sensation, the most trifling action impulse, thought, impression, or deed, can fade or go out from, or in the Universe. We may think it unregistered by our memory, unperceived by our consciousness, yet it will still be recorded on the tablets of the astral light. Personal memory is a fiction of the physiologist. There are cells in our brain that receive and convey sensations and impressions, but this once done, their mission is accomplished. These cells of the supposed "organ of memory" are the receivers and conveyors of all the pictures and impressions of the past, not their retainers. Under various conditions and stimuli, they can receive instantaneously the reflection of these astral images back again, and this is called memory, recollection, remembrance, but they do not preserve them. When it is said that one has lost his memory, or that it is weakened, it is only a facon de parler; it is our memory-cells alone that are enfeebled or destroyed. The window glass allows us to see the sun, moon, stars, and all the objects outside clearly; crack the pane and all these outside images will be seen in a distorted way; break the window-pane altogether and replace it with a board, or draw the blind down, and the images will be shut out altogether from your sight. But can you say because of this, that all these images - sun, moon, and stars - have disappeared, or that by repairing the window with a new pane, the same will not be reflected again into your room? There are cases on record of long months and years of insanity, of long days of fever when almost everything done or said, was done and said unconsciously. Yet when the patients recovered they remembered occasionally their words and deeds and very fully. Unconscious cerebration is a phenomenon on this plane and may hold good so far as the personal mind is concerned. But the Universal Memory preserves every motion, the slightest wave and feeling that ripples the waves of differentiated nature of man or of the Universe.
