This monologue is uttered at the beginning of the Formula of the Magician, with the operator witnessing upon the Mystical Tessera:

"Hastening the chariot of my heart's desire
My Goddess-guided powers have carried me
To find that inner road, that glorious road
Known to the wise. Hast thou not burned, my soul?--
Yea, chariot-wheels almost to flame aglow --
Seeking for my longed-for goal, the home of Truth?
From the Gates of Night I have come to the sill of Day,
I have passed the Brazen Door. She has grapsed my hand --
        The Goddess, my Queen --
And has bidden me still seek Truth on the inward road
Of Knowledge, while Opinion roams the world."

This is taken from the Greek mystical poet, Parmenides. A .PDF version of the text as well as an English translation of the poem is available at http://philoctetes.free.fr/parmenides.pdf .
