Asar and Asi—the Phallus and Vulva—paired with Sati, the Spine, form a triadic glyph of sexual polarity and axial structure. Asar (Osiris) represents the phallic principle, the generative, dying, and resurrecting force; Asi (Isis) embodies the vulva, the receptive, enveloping, and magical womb. Sati (the goddess Satis, or a play on the Egyptian set for ‘arrow’ or ‘shoot’) is the spine—the vertical axis that unites and channels these polar currents through the body’s central column.

Position on the Tree of Life

This triad corresponds to Yesod (9), the Foundation. Yesod is the lunar sphere of generation, the etheric double, and the seat of the reproductive organs. Here, the phallus and vulva are not merely physical but archetypal: they are the instruments of magical creation, while the spine is the conduit for the serpent-force (Kundalini) that rises from the base to the crown. In the microcosm, Yesod governs the genitals and the spinal column, making this correspondence a precise anatomical and energetic map.

Astrological and Planetary Correspondence

Yesod is ruled by the Moon, which governs tides, cycles, and the subconscious. The phallus and vulva, as lunar-solar polarities, reflect the interplay of receptive and projective forces. The spine, as the axis mundi of the body, aligns with the lunar current’s rhythmic flow—the ebb and surge of vital energy that underlies all generation.

Historical Context

The identification of Osiris with the phallus and Isis with the vulva is ancient. In Egyptian mythology, Osiris is dismembered by Set, and his phallus is eaten by a fish; Isis recovers and revivifies it, conceiving Horus. This myth encodes the death and renewal of generative power. Isis, as the Great Magician, is the vulva that receives and transforms—the womb of resurrection. The spine as Sati appears in later Hermetic and Thelemic synthesis, where the spinal column is the ‘wand’ of the microcosm, the physical correlate of the Tree of Life’s central pillar. In the Egyptian Book of the Dead, the spine is often depicted as a ladder or a djed pillar—the backbone of Osiris, symbolizing stability and the axis of ascent.

In the 777 system, this triad at Yesod (step 9) unites the generative organs with the axial skeleton. The phallus and vulva are the ‘foundation’ of physical creation; the spine is the ‘foundation’ of spiritual ascent. Together, they represent the perfected human—the being whose sexual force is transmuted into the light of consciousness via the spinal current. This is not a mere anatomical listing but a formula: the union of Asar and Asi generates the child Horus, while Sati provides the path for that energy to rise.

In Liber 777

At the 9th step (Yesod) of the row ‘The Perfected Man,’ this triad appears as the microcosmic counterpart to the macrocosmic forces of generation and stability. It is the body’s own temple, where the phallus and vulva are the holy of holies, and the spine is the pillar that connects earth to heaven.
