Ascend ... from the earth to heaven and then descend again to earth.

The riddle of the cross is contained in these words, and its double mystery is solved—to the Occultist.

The philosophical cross, the two lines running in opposite directions, the horizontal and the perpendicular, the height and breadth, which the geometrizing Deity divides at the intersecting point, and which forms the magical as well as the scientific quaternary, when it is inscribed within the perfect square, is the basis of the Occultist. Within its mystical precinct lies the master-key which opens the door of every science, physical as well as spiritual. It symbolizes our human existence, for the circle of life circumscribes the four points of the cross, which represent in succession, birth, life, death, and immortality.[1312]

“Attach thyself,” says the Alchemist, “to the four letters of the tetragram disposed in the following manner. The letters of the ineffable name are there, although thou mayest not discern them at first. The incommunicable axiom is kabalistically contained therein, and this is what is called the magic arcanum by the masters.”[1313]

Again:

The Tau, Τ, and the astronomical cross of Egypt, [Symbol: Circle with cross within] are conspicuous in several apertures of the remains of Palenque. In one of the basso-relievos of the Palace of Palenque, on the west side, sculptured as a hieroglyphic right under the seated figure, is a Tau. The standing figure, which leans over the first one, is in the act of covering its head with the left hand with the veil of initiation; while it extends its right with the index and middle finger pointing to heaven. The position is precisely that of a Christian bishop giving his blessing, or the one in which Jesus is often represented while at the Last Supper.[1314]

The Egyptian Hierophant had a square head-dress which he had to wear always during his functions. These square hats are worn unto this day by the Armenian priests. The perfect Tau—formed of the perpendicular (descending male ray) and the horizontal line (Matter, female principle)—and the mundane circle were attributes of Isis, and it was only at death that the Egyptian cross was laid on the breast of the mummy. The claim that the cross is purely a Christian symbol introduced after our era, is strange indeed, when we find Ezekiel stamping the foreheads of the men of Judah who feared the Lord,[1315] with the signum Thau, as it is translated in the Vulgate. In the ancient Hebrew this sign was formed thus [Symbol: Cross, tilted towards the northeast], but in the original Egyptian hieroglyphics as a perfect Christian cross ☦ (Tat, the emblem of stability). In the Revelation, also, the “Alpha and Omega”—Spirit and Matter—the first and the last, stamps the name of his Father on the foreheads of the elect. Moses[1316] orders his people to mark their door-posts and lintels with blood, lest the “Lord God” should make a mistake and smite some of his chosen people, instead of the doomed Egyptians. And this mark is a Tau!—the identical Egyptian handled cross, with the half of which talisman Horus raised the dead, as is shown on a sculptured ruin at Philæ.

Enough has been said in the text about the Svastika and the Tau. Verily may the cross be traced back into the very depths of the unfathomable archaic ages! Its mystery deepens rather than clears, as we find it on the statues of Easter Island, in old Egypt, in Central Asia, engraved on rocks as the Tau and Svastika, in Pre-Christian Scandinavia, everywhere! The author of the Source of Measures stands perplexed before the endless shadow it throws back into antiquity, and is unable to trace it to any particular nation or man. He shows the Targums handed down by the Hebrews, obscured by translation. In Joshua[1317] read in Arabic, and in the Targum of Jonathan, it is said: “The king of Ai he crucified upon a tree.”

The Septuagint rendering is of suspension from a double word or cross. (Wordsworth on Joshua.) ... The strangest expression of this kind is in Numbers(xxv. 4) where, by Onkelos (?) it is read: “Crucify them before the Lord (Jehovah) against the sun.” The word here is יקע, to nail to, rendered properly (Fuerst) by the Vulgate, to crucify. The very construction of this sentence is mystic.[1318]

So it is, but the spirit of it has been ever misunderstood. “To crucify before (not against) the Sun” is a phrase used of Initiation. It [pg 589] comes from Egypt, and primarily from India. The enigma can be unriddled only by searching for its key in the Mysteries of Initiation. The Initiated Adept, who had successfully passed through all the trials, was attached, not nailed, but simply tied on a couch in the form of a Tau, Τ, in Egypt, of a Svastika without the four additional prolongations (☩ not 卐) in India, plunged in a deep sleep—the “Sleep of Siloam,” as it is called to this day among the Initiates in Asia Minor, in Syria, and even higher Egypt. He was allowed to remain in this state for three days and three nights, during which time his Spiritual Ego was said to “confabulate” with the “Gods,” descend into Hades, Amenti, or Pâtâla—according to the country—and do works of charity to the invisible Beings, whether Souls of men or Elemental Spirits; his body remaining all the time in a temple crypt or subterranean cave. In Egypt it was placed in the Sarcophagus in the King's Chamber of the Pyramid of Cheops, and carried during the night of the approaching third day to the entrance of a gallery, where at a certain hour the beams of the rising Sun struck full on the face of the entranced Candidate, who awoke to be initiated by Osiris and Thoth, the God of Wisdom.
