What do people mean by like "dont go to the light" when they are dying. Does this have anything to do with Satan?

So I got Chronos XP and it tells me what hour of what planet and what day it is but how does this help me with my magic?

So I am trying to dedicate my soul but I can not obtain the physical things needed so I am doing so in my astral temple can I read The prayer from the site aloud and visualize me burning it written and signed in my blood or whould I myself have to write and read it from memory in my astral temple?
