90 is the numeration of the Hebrew letter Tzaddi (צ), a letter that carries the dual meaning of a 'fishhook' and a 'righteous one' (Tzaddik). Its primary astrological correspondence in the Hermetic Qabalah is the zodiacal sign Aquarius. This number is also intimately linked with the Atu of the Tarot, The Star, a card of hope, divine inspiration, and the pouring forth of celestial waters.

Position on the Tree of Life

This value of 90 appears at the 29th step of the scale, which corresponds to the 29th Path on the Tree of Life. This is the Path of Tzaddi, connecting the Sephirah of Netzach (Victory) to the Sephirah of Yesod (Foundation). This position bridges raw, natural force with the astral foundation, purifying it into a stream of cosmic consciousness.

Astrological and Planetary Correspondence

The number 90 is fixed to Aquarius, an air sign ruled by Saturn (in traditional astrology) and Uranus (in modern). It is not a planetary number itself, but the value of the letter that governs that sign. This reinforces the 90's nature as an intellectual, fixed, and revolutionary energy, concerned with the distribution of knowledge (water poured from the Star's jars) and the dissolution of old forms.

Historical Context

The gematria of 90 appears in several significant scriptural contexts. The word Tzaddik (צדיק), meaning 'righteous one', sums to 90. This forms the foundation of the Kabbalistic concept of the Lamed-Vav Tzaddikim—the 36 hidden righteous individuals for whose sake the world is sustained. In a more esoteric context, the phrase 'Mei Menuchot' (waters of rest) from Psalm 23:2 also equals 90, linking the number directly to The Star's imagery of peaceful, restorative waters. Within the structure of Liber 777, 90 is the value assigned to the 29th Path, solidifying its role as the key to this specific current of spiritual energy.

At the step of Hod (8) on the scale of numeration, the number 90 represents the intellectual glory and splendor of this Aquarian current. It is the distilled, abstract essence of the Tzaddi force—the 'righteous' structure of inspired law and the 'fishhook' of wisdom that draws truth from the supernal depths into the mind. In this column, 90 is the key that locks and unlocks the Path of the Star.
