The English vowel E (as in they, the long sound, not the short eh) represents the letter Ayin in the Hebrew alphabet, which is attributed to the 26th Path of the Tree of Life (the path connecting the sephirah Yesod to Tiphereth). In the system of Liber 777, this particular column (LI) is the 'English Equivalent' column, which vocalises the Hebrew letters as pure sounds. Here, E is the specific vowel sound of Ayin, functioning as a phonetic glyph representing a particular state of vibration and consciousness. It occupies the seventh step of the scale, which corresponds to the sephirah Netzach (Victory), indicating that this sound emanates from the sphere of natural desire and the instincts of the subconscious under the guidance of the will.

In Egyptian mythology, this same letterform is the hieroglyph of the eye (the organ of Ayin), the symbol of the god Horus. In the Greek alphabet, it is Epsilon, the first vowel of the name Eris and the letter of the goddess of strife and discord, who in the Qabalah is the Queen of the Qliphoth. However, in the Qabalistic tradition of the Sepher Yetzirah, Ayin is the 'Son of Silence,' the single vowel that can be produced by the mouth without contact of the tongue or lips, representing the pure vowel of the throat, the 'breath of the voice of the Lord.' The correspondence to the 'Eye' (Ayin as the physical eye) is a mystery: this vowel is the sound of the eye seeing the light, a silent, vibrant 'E' that is the sound of the universe seeing itself. In the 777 system, it is the 'Long E,' contrasting with the 'Long O' of Vau and the 'Broad A' of Aleph, completing the three macroprosopic vowel-sounds of the ineffable Name IHVH (Yod-He-Vau-He), where the final He is the silent sh’va, and the E of Ayin is not part of the Name but the sound that emerges when the Name is breathed with the eye.

At the scale step of Netzach (Victory), this vowel is the sound of the ever-flowing, magnetic, psychic current of nature—the tune that the spider's string sings, the sound of the landscape's magnetic field. In the table of 777, this E is the phonetic key to the 26th Path, which is the path of the Fool (Atu 0) and the letter Aleph when considered in the system of the 'turning of the Ayin,' a secret permutation of the Tarot. It is the sound of the laughter of the Fool as he steps off the cliff, the 'E!' of surprise and the 'E' of the perfect, continuous vowel of the void's own internal hum.
