If you don’t, you are putting yourself in a prison and that prison is inside of your head. Evil is nothing more than fear. Fear gives power over to evil. Then, bad things happen in your life over and over and over again until you finally say, “you know what… I give in. I give up my attempt at control.”
Although Fire destroys, it also lays the foundation creation by burning down. This is a process of death and rebirth. Fire is slow to begin, but once it is confident in itself, it sparks and and burns whatever touches it. If, however, it becomes too sure of itself, or too egotistical, it runs out of things to burn and turns to ashes instead.
