 IKH = Sagittarius, Fire, Air = סשא = 361. These three numbers represent the Supernal Triad, the Hexagon and Malkuth — the arrangement of the Tree of Life:
(3) Supernal Triad = Kether, Chokmah and Binah.
(6) Hexagon = Chesed, Geburah, Tiphareth, Netzach, Hod and Yesod.
(1) One = Malkuth, pendant to the other 9 Sephiroth.
Also 361 = Adonai ha-Aretz. For it is the formulation of the Sephiroth which is a barrier of organic structure against the confusion of matter.
 A Kamea is a "magic square" containing the letters corresponding to the numbers (in this case from 1 to 81); so arranged that each line, vertical or horizontal, shall add to the same total. (See Vol. 4 of The Golden Dawn for the Kameas attributed to each of the planets.)
 Shu is in Yesod, as the supporter of the Tree of Life, and he is Zeus, the Lord of Air. But also Zeus is the orderer of all things.
 Yesod = 9.
 Silver for the moon of Yesod.
 Yesod is Air.
 Both Air and Moon are in Yesod, Stability.
 9 x 7 = 63. 6 plus 3 = 9. 9 x 127 = 1143. 1 plus 1 plus 4 plus 3 = 9.
 "For they cross with the currents reflected." This is a description of the Tree of Life; see diagram. See also the essay on the Tree of Life entitled Hodos Chameleonis in Vol. 1, Golden Dawn, where the above phrase is first used.
 The 72 pearls are the quinaries (divisions of 5° in each Sign) of the Zodiac. They appear in the Atu XXI — the Universe. See Liber CCXXXI (Equinox I, vii), v. 21.
 Full title of Yesod is Tzedeq Yesod Olahm, "The Righteous is the Foundation of the World."
 I.S.V.D. = Yesod = 80, the number of Peh, the letter of Mars.
 This is the danger which threatens all aspirants to the Grade of Magister Templi. Woe to those who accept it lightly, or without the fullest preparation. If any trace of egoism persists, the whole attainment is negated and succeeded by corruption.
 "My God, my God, why hast thou forsaken me?"
