“For God is, in His Essence, holy above ascent and descent, entrance and exit; He hath through all eternity been free of the attributes of human creatures, and ever will remain so. No man hath ever known Him; no soul hath ever found the pathway to His Being.
‘Every mystic knower hath wandered far astray in the valley of the knowledge of Him; every saint hath lost his way in seeking to comprehend His Essence. Sanctified is He above the understanding of the wise; exalted is He above the knowledge of the knowing! The way is barred and to seek it is impiety; His proof is His signs; His being is His evidence (Sermon by Ali).
“Wherefore, the lovers of the face of the Beloved have said: “O Thou, the One Whose Essence alone showeth the way to His Essence, and Who is sanctified above any likeness to His creatures.” How can utter nothingness gallop its steed in the field of preexistence, or a fleeting shadow reach to the everlasting sun? The Friend (the Prophet Muhammad) hath said, “But for Thee, we had not known Thee,” and the Beloved (the Prophet Muhammad) hath said, ‘nor attained Thy presence.'”
-(The Valley of Unity, ‘The Seven Valleys and the Four Valleys’ , Baha’u’llah)
