THE DIFFERENT CATEGORIES OF INHABITED WORLDS
3. As a result of Spirit teaching, we know that the conditions of the various worlds differ one from the other, with respect to the degree of elevation or inferiority of their inhabitants, amongst whom are those inferior to the inhabitants of Earth, both physically and merrily; some in the same category, yet others which are more or less superior in every aspect In the inferior worlds, existence is all material, passions are sovereign and morality is almost nil. At the same time as the soul is progressing the material influences diminish, to such an extent that in the elevated worlds life is, by way of saying, all spiritual.
4. In the intermediate worlds good is mixed with evil, one or the other predominating according to the degree of advancement of the majority of the inhabitants. Although it is not possible to make an absolute classification of the different worlds, we can at least divide them in general terms by virtue of the state in which they are in, and the destiny they bring with them, based on the most predominant features upon each planet in the following manner: primitive worlds, destined to receive the initial incarnations of the human soul; worlds of tests and atonements, where evil predominates; regenerating worlds, where souls who still have to atone may absorb new strength by resting from the fatigue of fighting; blessed worlds, where goodness outweighs evil; celestial or divine worlds, inhabited by purified Spirits, where only goodness exists. Earth belongs to the category of worlds of tests and atonements, which is why mankind lives encompassed by such misery.
5. Spirits who find themselves incarnated in any world are not bound to that same world indefinitely, nor do they go through all the phases of progress needed to achieve perfection in that one world. When they reach the maximum degree of advancement their world has to offer, they then pass on to a more elevated one, and so on successively till they reach the state of purified Spirits. These different worlds are stations where the Spirits find the elements they need for their progress that are in accordance to their degree of perfection. It is a recompense to ascend to a world of higher elevation, just as it is a punishment to prolong their stay in a miserable world, or to be relegated to another even more unhappy than the one they were forced to leave, due to persisting badness.
