The following has been pulled from what was originally a Twitter thread, please forgive the formatting.
1. Hades shares the river Oceanus with Earth, Earth contained within Oceanus’ circle while Hades lies beyond Oceanus. Seeing Earth is the 3rd dimension, this makes Hades the 4th dimension as it is the next beyond the 3rd.
2. Excluding Oceanus since Hades shares this river with Earth, Hades has 5 rivers. If we expand the Pythagorean tetractys beyond its last dimension of 4 points, this which Pythagoras called kosmos, to create a 5th line (the 4th dimension) to account for Hades, it has 5 points.
3. The tetractys, when we advance its dimensional complexity from 0 to 3, ends in the tetrahedron. When we advance it once more (pictured under point 4) to get the 4th dimension (Hades), we have the pentachoron.
4. Turning the pentachoron into a net, we have the 5-cell coxeter helix; into an orthogonal projection, the pentagonal frame below. The curiosity here, as likely obvious, is the formation of the mystically significant pentagram. The five lines are the five rivers of Hades.
5. The pentagram is entangled with cosmic meaning. Pherecydes of Syros says in his cosmogony “the divine products of Chronos’ seed, when disposed in five recesses, were called Pentemychos”. Greeks often took Chronos and Kronos as the same, so he here is embedded in Tartarus.
6. But what is most significant, and will soon be seen as complementary to the pentagram’s cosmic meaning, is the net’s consistency with Kabbalah’s tree of life. As clearly seen when put together in the image below, the parallel cannot be mistaken.
7. The tree of life is comprised of 10 sefirot linked by paths which are said to lead upwards (when considered from humanity’s position at the bottom) from Malchut (Kingdom) or finite creation, to Keter (Crown) or the ineffable. Tiferet, unlike the others, has 5 paths ‘upwards’.
8. To show the 5 paths correlate with Hades’ 5 rivers, we remind ourselves of the earlier image showing increasing dimensional complexity within the Pythagorean tetractys, from 0D to 3D. Knowing Malchut as finite creation, we transpose the 3rd dimension onto its constituents.
9. Then, taking Tiferet as Hades, we should expect to do as we did with Malchut: we transpose the 4th dimension onto its constituents and find consistency in our method. Only Kether is left without connex, and so becomes consistent with Kabbalah’s assignment of ineffability.
10. What does it mean? We know by tradition the place of Hades: it is the realm of the dead; soul is there after embodied life is lost. To remain there is punishment by isolation, and in Tartarus the wicked suffer, but usually souls drink of Lethe (forgetfulness) and reincarnate.
11. It is no doubt cosmic, though it is non-physical. It is soul when not embodied but still separate from union with the gods. If our souls were to pursue the end of Hades, it would flow with fiery river Phlegethon into Tartarus, abode of Kronos.
12. Kronos, though king of Tartarus according to Homer, is so deep within the abyss of Tartarus that Odysseus found neither him nor the Titans in his venture to the underworld. These Titans reflect the ineffability of pure Matter, or non-being: the mundane prior to form.
13. This is the hidden truth of Kabbalah. It is a deception. The discipline exists to lure the soul deeper into the cosmos, to turn worship to the lowest and not to the highest. It confuses the ineffable One for the ineffable Many, hence they speak of “the many names of God”.
14. Iamblichus numbered the sub-lunar beings of cosmos at 72, and in tandem Kabbalah calls God by 72 names. By subversion of religion, sub-lunar forces (daemons) excellently deceive souls with deception, promise, and confusion so that they never reunite with the gods.
15. This purpose is fulfilled not just in Kabbalah, but also through the Abrahamic faiths derived from Kabbalah’s religion. Common to them all is the promise of a “world to come”, a New Earth of God’s creation wherein the faithful enjoy a perfect life and immortality.
16. And how does Kabbalah describe Tiferet, the sefira we found to be certainly Hades?
As written in the Bahir: “Sixth is the adorned, glorious, delightful throne of glory, the house of the world to come.”
Do not be seduced, return to the gods.
