Say again: 'Silence, silence.' And when the disk opens, you will see a fireless ring and fiery doors shut fast. At once recite the following formula, closing your eyes. Third formula:

The vision reaches a shut door. Through the opened disk the initiate sees a fireless ring (ápyron) and, within it, fiery doors closed fast — the paradox held in two words, a circle without fire ringing gates made of fire. He has come as far as looking will take him; the next threshold does not yield to sight. So the instruction is the opposite of everything before: close your eyes and drive the formula through (díōke, the verb for urging horses on — recite it fast and hard). Where the ascent has been all seeing — you will see, you will see — the final approach is made blind, by voice alone. The eyes that were opened to behold the immortal now shut, and the third and greatest invocation, the fire-god's, begins in the dark.
