Part 1: The passages through which the lights pass... The way in which the inner light emerges through the apertures of the face is not merely haphazard as in the case of a blazing fire covered by a perforated vessel, through which the light of the fire emerges wherever there is a hole. Had this been the way the inner light emerged, it would have had two results, both of which we know not to be the case.
Firstly, since it is the same fire under all the holes, what emerges through each hole is also entirely uniform: the fire does not take on any new movements in order to exit via particular locations that might cause it to undergo some kind of change. Rather, the fire leaves wherever it finds a hole, and it passes through one hole in exactly the same way as it would leave through any other. Secondly, the fire standing covered under one hole passes out through that hole, while the fire standing under a different hole passes out there: the fire does not undergo any kind of change causing what is under one hole to go out via another.
