As Christ is unto the Word of Light, so there is an inversion of the Logos which is mythological transcribed as the twins or the Lion and the Serpent or Dragon. The key of the Victory of Christ is the (eventual) unification of the Christic-Luciferic Logos, the One Word of the Father. As the magus ascends unto the rarified reaches of existence, the two shall be seen to first overlap and then to be joined in mutual orbit, as a binary star system is, and then to be aspects of the singular Logos of the Pleroma. Thus it is understood that the walker of the Path must work with both formulae, positive or Christ and negative or Lucifer. Thus, irregardless of the nonsense about the Devil or demonolatry or what have you, the Left hand current I equally important for those that would gain the Height.

The Lion/Serpent is a symbol of ancient pedigree. It is found in the Mitra cult as well as Egyptian and Gnostic iconography.
…
The name of the Hebrew letter Teth means serpent, and Teth is attributed to the zodiacal sign of Leo, the lion. Teth corresponds to the Tarot Trump called "Lust," or, in the old system, "Strength." This Trump depicts the relationship between CHAOS and BABALON.
While the Lion and the Serpent are both associated with Teth/Leo, the serpent is also a symbol of the zodiacal sign Scorpio. Leo and Scorpio are both Fixed Signs, but whereas Leo is a fiery sign, ruled by the Sun, Scorpio is a watery sign, ruled by Mars (or Pluto), and Scorpio and Leo are located square to each other on the wheel of the zodiac. Also, Scorpio is attributed to the Hebrew letter Nun, which corresponds to the Tarot Trump called "Death." Leo can be viewed as representing the conscious Will, or the Will to Live, Scorpio can be viewed as representing the unconscious Will, or the Will to Die.
Therefore the complex is a manifestation of the sexual/survival instinct. Indeed this symbolism is found, in whole or in part operating in practically all major myth-cycles.
Crowley adapted this symbolism for his Gnostic Mass and also for the foundation of his understanding of Baphomet. Crowley devised this theoretical view as: BAFOMIThR = Father (of) Mithra; also 8 letters indicates Mercury; also 729 = Kephas, stone, the name Jesus gave Peter as the founder of the Church, the Cubic Stone which was the Corner of the Temple; also the inverted pentagram, the hermaphrodite fully grown; also the original being, Zeus Arrhenothelus or Bacchus Diphues; also the Androgyne, the hieroglyph of arcane perfection; also the emblem of Pan Pangenetor as symbolized by Atu XV, the "Devil" Trump of the Tarot.(1)
As noted, Levi wrote concerning Baphomet and his glyph of the gos/demon is the most famous representation of him by far.
(I)n his now famous drawing of "The Devil" of the Tarot, a winged, goat-headed being with human female breasts and a Caduceus for a phallus, seated upon a cubic stone which rests upon a globe, with its right arm raised toward a waxing crescent moon and inscribed solve, its left arm lowered toward a waning crescent moon and inscribed coagula, a flaming torch between its horns and an upright pentagram on its forehead.
Baphomet is the Union of Opposites: Synthesis of Thesis and Antithesis, Chokhmah and Binah united in Tiphareth; the sperm and egg united in the zygote; Yod the Father and Heh the Mother united in Vav the Son; etc.
The idea is found in the school of Simon Magus as the fragmentary text Apophasis Megalê shows; Baphomet is the Father, the Demiurge which manifests in the Middle Space between the male Great Power and the female Great Thought.
