The Soul After Death
149. What becomes of the soul at the moment of death?'
"It becomes again a spirit; that is to say, it returns into the world of spirits, which it had quitted for a short time."
150. Does the soul, after death, preserve its individuality?'
"Yes, it never loses its individuality. What would the soul be if it did not preserve it?"
- How does the soul preserve the consciousness of its individuality, since it no longer has its material body?'
"It still has a fluid peculiar to itself, which it draws from the atmosphere of its planet, and which represents the appearance of its last incarnation-its perispirit."
- Does the soul take nothing of this life away with it?
"Nothing but the remembrance of that life and the desire to go to a better world. This remembrance is full of sweetness or of bitterness according to the use it has made of the earthly life it has quitted. The more advanced is the degree of its purification, the more clearly does it perceive the futility of all that it has left behind it upon the earth."
151. What is to be thought of the opinion that the soul after death returns to the universal whole?
"Does not the mass of spirits, considered in its totality, constitute a whole? Does it not constitute a world? When you are in an assembly you form an integral part of that assembly, and yet you still retain your individuality."
152. What proof can we have of the individuality of the soul after death?
"Is not this proof furnished by the communications which you obtain ? If you were not blind, you would see; if you were not deal you would hear; for you are often spoken to by a voice which reveals to you the existence of a being exterior to yourself."
Those who think that the soul returns after death into the universal whole are in error if they imagine that It loses its Individuality, like a drop of water that falls Into the ocean they are right If they mean by the universal whole the totality of Incorporeal beings, of which each soul or spirit Is an element.
If souls were blended together Into a mass, they would possess only the qualities common to the totality of the mass there would be nothing to distinguish them from one another, and they would have no special, intellectual, or moral qualities of their own. But the communications we obtain from spirits give abundant evidence of the possession by each spirit of the consciousness of the me, and of a distinct will, personal to itself; the infinite diversity of characteristics of all kinds presented by them Is at once the consequence and the evidence of their distinctive personal individuality. If, after death, there were nothing but what is called the "Great Whole," absorbing all individualities, this whole Would be uniform in its characteristics and, in that case, all the communications received from the invisible world would be identical. But as among the denizens of that other world we meet with some who are good and some who are bad, some who are learned and some who are ignorant, some who are happy and some who are unhappy, and as they present us with every shade of character, some being frivolous and other. serious, etc., it is evident that they are different individualities, perfectly distinct from one another. This individuality becomes still more evident when they are able to prove their identity by unmistakable tokens, by personal details relating to their terrestrial life, and susceptible of being verified; and it cannot be a matter of doubt when they manifest themselves to our sight under the form of apparitions. The individuality of the soul has been taught theoretically as an article of faith; Spiritism renders it patent, as an evident, and, so to say, a material fact.
