An interesting topic for discussion. The fire is completely real and at the same time not quite material. He comes from heaven as a messenger of higher powers, and then he is unbridled and destructive. And at the same time it can be mined, saved, managed. Fire simultaneously destroys, burns - and warms, gives food and protection. And fire is like a living creature: it can be born, eat, die. In short, fire is a mystery to me :)
