God, the unknowable Essence

A most beautiful verse from the Gleanings From the Writings of Bahá’u’lláh (bear in mind that this is Baha'u'llah, the Manifestation of God, himself talking about God):

"How bewildering to me, insignificant as I am, is the attempt to fathom the sacred depths of Thy knowledge! How futile my efforts to visualize the magnitude of the power inherent in Thine handiwork—the revelation of Thy creative power! How can mine eye, which hath no faculty to perceive itself, claim to have discerned Thine Essence, and how can mine heart, already powerless to apprehend the significance of its own potentialities, pretend to have comprehended Thy nature? How can I claim to have known Thee, when the entire creation is bewildered by Thy mystery, and how can I confess not to have known Thee, when, lo, the whole universe proclaimeth Thy Presence and testifieth to Thy truth?"
