“Why Do We Not Remember Our Past Lives?”
“Enq: You just said that the SPIRITUAL EGO was omniscient. Where, then, is that vaunted omniscience during the Devachanic life, as you call it?
Theo: During that time it is latent and potential, because, first of all, the Spiritual Ego (the compound of Buddhi-Manas) is not the Higher SELF, which being one with the Universal Soul or Mind is alone omniscient;
and, secondly, because Devachan is the idealized continuation of the terrestrial life just left behind, a period of retributive adjustment, and a reward for unmerited wrongs and sufferings undergone in that special life.
It is omniscient only potentially in Devachan, and de facto exclusively in Nirvana, when the Ego is merged in the Universal Mind-Soul.
Yet it rebecomes quasi omniscient during those hours on earth when certain abnormal conditions and physiological changes in the body make the Ego free from the trammels of matter.
Thus the examples cited above of somnambulists, a poor servant speaking Hebrew, and another playing the violin, give you an illustration of the case in point.
This does not mean that the explanations of these two facts offered us by medical science have no truth in them, for one girl had, years before, heard her master, a clergyman, read Hebrew works aloud, and the other had heard an artist playing a violin at their farm.
But neither could have done so as perfectly as they did had they not been ensouled by THAT which, owing to the sameness of its nature with the Universal Mind, is omniscient.
Here the higher principle acted on the Skandhas and moved them; in the other, the personality being paralyzed, the individuality manifested itself. Pray do not confuse the two.”
