The Body as Sepulcher of the Soul

Μαρτυρεοντα δε και οι παλαιοι ϑεολογοι τε και μαντιες, ὡς δια τινας τιμωριας, ἁ ψυχα τῳ σωματι συνεζευκται, και καϑαπερ εν σωματι τομτῳ τεϑαπται.

The ancient theologists and priests also testify that the soul is united with the body as if for the sake of punishment;  and so is buried in body as in a sepulchre. – Philolaus

Speaking of Souls Unembodied

“We live their death, and we die their life.”
Ζωμεν τον εκεινων ϑανατον, τεϑνηκαμεν δε τον εκεινων βιον.

Heracleitus

Generation

And Empedocles, deprecating the condition termed “generation,” beautifully says of her:
The aspect changing with destruction dread,
She makes the living pass into the dead.
Εκ μεν γαρ ζωων ετιϑει νεκρα ειδε αμειβων (And for he who lives and sees the dead, he will be rewarded).

And again, lamenting his connection with this corporeal world, he pathetically exclaims:
For this I weep, for this indulge my woe,
That e’er my soul such novel realms should know.
Κλαυσα τε και κωκυσα, ῶων ασυνηϑεα χωρον (I cried and cried, in an unusual place).

Sons of Light

That which is meant by the allegorical sentence, “Fiat Lux,” is, when esoterically rendered, “Let there be the ‘Sons of Light’,” or the Noumena of all phenomena. Thus the Roman Catholics rightly interpret the passage as referring to Angels, but wrongly as meaning Powers created by an anthropomorphic God, whom they personify in the ever thundering and punishing Jehovah.

These beings are the “Sons of Light,” because they emanate from, and are self-generated in, that infinite Ocean of Light, whose one pole is pure Spirit lost in the absoluteness of Non-Being, and the other pole, the Matter in which it condenses, “crystallizing” into a more and more gross type as it descends into manifestation. Therefore Matter, though it is, in one sense, but the illusive dregs of that Light whose Rays are the Creative Forces, yet has in it the full presence of the Soul thereof, of that Principle, which none—not even the “Sons of Light,” evolved from its Absolute Darkness—will ever know.
