Soon afterward my blood and the whole world began to circulate a thousand times faster; the earth seemed to be flying, light as down. And within me everything was simple, light and clear. Only then I noticed on the rock the familiar, enormous letters: M E P H I , and for some reason the inscription seemed to me necessary . It seemed to be a simple thread binding everything together. A rather rough picture hewn in the rock; this too, seemed comprehensible; it represented a youth with wings and with a transparent body, and in the place ordinarily occupied by the heart⁠—a blinding, red, blazing coal. Again, I understood that coal, or no, I felt it as I felt without hearing every word of I-330 (she continued to speak from above, from the rock), and I felt that all of them breathed one breath and that they were all ready to fly somewhere like the birds over the Wall.
