The Religion is heavily associated with fire, as the people believe that fire represents peoples thoughts and emotions, both good and bad. It can create and destroy so fire isn't a good thing like light is, nor is it a bad thing like darkness.
More than anything else, the fire represents change. It's constantly flickering and shifting. Since the fire is a representation of peoples thoughts,it tells them that they can change. Only when a person dies does the fire go out.
