“That which survives as an individuality after the death of the body is the astral soul, which Plato, in the Timaeus and Gorgias, calls the mortal soul, for, according to the Hermetic doctrine, it throws off its more material particles at every progressive change into a higher sphere.
Socrates narrates to Callicles that this mortal soul retains all the characteristics of the body after the death of the latter; so much so, indeed, that a man marked with the whip will have his astral body “full of the prints and scars.” The astral spirit is a faithful duplicate of the body, both in a physical and spiritual sense.
The Divine, the highest and immortal spirit, can be neither punished nor rewarded. To maintain such a doctrine would be at the same time absurd and blasphemous, for it is not merely a flame lit at the central and inexhaustible fountain of light, but actually a portion of it, and of identical essence. It assures immortality to the individual astral being in proportion to the willingness of the latter to receive it.
So long as the double man, i.e., the man of flesh and spirit, keeps within the limits of the law of spiritual continuity; so long as the divine spark lingers in him, however faintly, he is on the road to an immortality in the future state.
But those who resign themselves to a materialistic existence, shutting out the divine radiance shed by their spirit, at the beginning of the earthly pilgrimage, and stifling the warning voice of that faithful sentry, the conscience, which serves as a focus for the light in the souls – such beings as these, having left behind conscience and spirit, and crossed the boundaries of matter, will of necessity have to follow its laws.”
