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.
