ההאי (Heh-Heh-Aleph-Yod) is a four-letter permutation of the Tetragrammaton (YHVH), specifically the form that appears in the ninth revolution of the divine name in the world of Briah (Creation). Its letters—Heh, Heh, Aleph, Yod—encode a specific sequence of the divine forces as they descend through the sephiroth. Etymologically, it is a variant of the name היהא (Heh-Yod-Aleph-Heh), which itself is a permutation of the Tetragrammaton, and the doubling of the Heh emphasizes the formative, lunar aspect of this revolution.

Position on the Tree of Life

This permutation corresponds to the ninth sephirah, Yesod (Foundation), on the Tree of Life. Yesod is the sphere of the moon, the astral plane, and the subconscious. The revolution of the name at this step represents the stabilization and reflection of the divine light into a receptive, formative vessel. The double Heh (הה) in the name underscores the lunar, receptive quality of Yesod, while the Aleph (א) and Yod (י) introduce the principles of unity and active potential, respectively.

Astrological and Planetary Correspondence

Yesod is governed by the moon, and this permutation aligns with the lunar cycle of the divine name. The revolution of היהא in Briah at this step corresponds to the waning or dark phase of the moon, where the light is hidden and the foundation is prepared for the next cycle. The double Heh reflects the moon's reflective nature, while the Aleph and Yod hint at the hidden solar and active principles within the lunar sphere.

Historical Context

The concept of the 231 permutations of the Tetragrammaton, including the revolutions of היהא in Briah, originates in the Kabbalistic tradition of the Sefer Yetzirah and later medieval commentaries. These permutations are used as a meditative and magical technique to explore the different aspects of the divine name as it manifests through the sephiroth. The specific sequence of revolutions in Briah is detailed in the works of the 16th-century Kabbalist Rabbi Isaac Luria (the Ari) and his school, particularly in the writings of Hayyim Vital. The permutation at the ninth step, ההאי, is associated with the foundation of the astral world and the formation of the subconscious. In the Hermetic Order of the Golden Dawn, these permutations were incorporated into the system of correspondences in Liber 777, where they are linked to the sephiroth and their associated symbols.

Closing

In Liber 777, at the ninth step (Yesod) of the row "The Revolutions of היהא in Briah," the named subject is the permutation ההאי. This represents the lunar, foundational aspect of the divine name in the world of creation, serving as a key to the astral and subconscious forces.
