“Matter is as indestructible and eternal as the immortal spirit itself, but only in its particles, and not as organized forms. The body of so grossly materialistic a person as above described, having been deserted by its spirit before physical death, when that event occurs, the plastic material, astral soul, following the laws of blind matter, shapes itself thoroughly into the mould which vice has been gradually preparing for it through the earth-life of the individual.
Then, as Plato says, it assumes the form of that “animal to which it resembled in its evil ways” during life. “It is an ancient saying”, he tells us, “that souls departing hence exist in Hades and return hither again and are produced from the dead…But those who are found to have lived an eminently holy life, these are they who arrive at the pure abode ABOVE and DWELL ON THE UPPER PARTS of the earth” (the ethereal region).
In Phaedrus, again, he says that when man has ended his first life (on earth), some go to places of punishment beneath the earth. This region below the earth, the kabalists do not understand as a place inside the earth, but maintain it to be a sphere, far inferior in perfection to the earth, and far more material.
Of all the modern speculators upon the seeming incongruities of the New Testament, alone the authors of the Unseen Universe seem to have caught a glimpse of its kabalistic truths, respecting the gehenna of the universe.
This gehenna, termed by the occultists the eighth sphere (numbering inversely), is merely a planet like our own, attached to the latter and following it in its penumbre; a kind of dust-hole, a “place where all its garbage and filth is consumed”, to borrow an expression of the above-mentioned authors, and on which all the dross and scorification of the cosmic matter pertaining to our planet is in a continual state of remodeling.”
