Perception of the Nature of Thought

If one would study the laws of the Old Moon existence—or at any rate a part of them—purely physiologically and not clairvoyantly, the only way to do so today would be to study the laws at work in the sheaths surrounding the human embryo before it draws the first breath, enfolding it and nourishing it. What is there enclosed in the mother's body, what can only thrive during earthly evolution within the protecting sheath of the maternal body was the whole nature during the Old Moon evolution; it filled the whole field of vision.
