Ya (יה) is the divine name composed of the Hebrew letters Yod (י) and Heh (ה). It is the earliest and most concentrated form of the Tetragrammaton (יהוה), a theonym so potent it was never vocalised. The name means "He Who Is" or "The Existent," and its two letters represent the seminal, masculine principle of creation: Yod as the seed, Heh as the vessel of emanation.

Οn the Tree of Life, this name is bound to the second Sephirah, Chokmah (Wisdom), the first flash of active, differentiating force from the unity of Kether. As the God-Name in Assiah (the material world of action), Ya anchors the highest wisdom into the densest plane of existence.

Astrological and planetary correspondence

Chokmah is attributed to the sphere of the Zodiac (the Mazloth), the wheel of fixed stars. This is not a planetary influence but the primal, bounding light of the heavens themselves—the first articulated circle of time and fate. Ya, as its name, is the sound of that ring's first turning.

Historical context

In the Hebrew Bible, the name Ya appears primarily as a poetic abbreviation, especially in the Hallelujah formula (הללו־יה — "Praise ye Yah"). The earliest strata of Exodus (15:2) and Isaiah (12:2) preserve it as a cry of salvation: "Yah is my strength and my song." The Egyptian execration texts of the 19th century mention a related form among the Shasu nomads, but the spelling flourished in the post-Exilic period. Philo of Byblos, citing the Phoenician priest Sanchuniathon, records that the Jewish mysteries taught that the name first emerged from the ineffable chaos as a single point of light. By the third century, the rabbinic tradition in the Jerusalem Talmud declared that the Name of Four Letters was read aloud only once a year by the High Priest—but the Two-Letter Name was the secret key whispered by the angels when they ascended the firmament. The Alexandrian Gnostics revered it as the root-utterance of the Aeon; in the Greek Magical Papyri, it is inscribed on lamellae as IAΩ, a syllable of power for invoking the Demiurge.

Closing

In the table of Liber 777, the assigned divine name for Sephirah 2 (Chokmah) in the column "God-Names in Assiah" is Ya (יה). It stands as the first articulated breath of the Absolute, spoken into the world of action.
