what warms us when we're cold.
what we use to cook much of our food.
how we incinerate stuff we don't want around anymore.
what we do when we discharge a weapon.
when we terminate someone's employment.
Fire is a tool for our use (both in its noun and verb forms). As with all tools, we get to decide whether that use is for purposes good or bad.
Metaphorically, fire is what burns deep inside of us, providing the passionate connection to our goals, our dreams, and the ones we love.
That metaphorical fire can and often does go out, but only if we quit purposefully stoking it.
Still, the choice is ours.
