Heh (ה) is the fifth letter of the Hebrew alphabet, with a numeric value of 5. Its name means ‘window’ or ‘breath,’ evoking the idea of an opening through which spirit or air passes. In the Sepher Yetzirah it is one of the twelve simple letters, attributed to the zodiac sign Aries and to the sense of sight.

Position on the Tree of Life

Heh is assigned to Path 15, which connects Chokmah (Wisdom) to Tiphareth (Beauty) on the Tree of Life. This path is the first of the three ‘Mother Letters’? No, that is Aleph, Mem, Shin. Heh is simple. Its astrological correspondence is Aries, the Ram, a fire sign ruled by Mars, giving the path a dynamic, assertive quality.

Astrological and planetary correspondence

In the system of Liber 777, Heh corresponds to the zodiac sign Aries (♈) and, by extension, to the planet Mars (♂) as its ruler. This attribution aligns with the letter’s symbolism of forceful, outward-directed energy—a window that lets in light and breath, but also a portal for action.

Historical context

Heh appears in the Sefer Yetzirah as one of the twelve simple letters that ‘engrave’ the universe, each governing a direction, a sense, and a zodiacal sign. In the Zohar, Heh is linked to the divine name YHVH, where it represents the second and fourth letters, symbolizing the womb and the material world. The shape of the letter—a roof with a gap at the lower left—is said to depict a window or an opening, reinforcing its role as a conduit between the inner and outer. In later Kabbalistic tradition, Heh is associated with the sefirah of Binah (Understanding) when considered as the ‘supernal Heh,’ and with Malkuth (Kingdom) as the ‘lower Heh.’

In the 777 table, at scale step 15 (Path 15), the Hebrew letter Heh is the entry under the column ‘Hebrew Letters,’ standing as the glyph that mediates between the supernal and the middle pillars. Its presence here anchors the correspondences of the path: the zodiac sign Aries, the number 5, and the elemental fire of the Ram.
