The fire changes. A fire is never the same from one instant to the next. It is hard to tell if the fire has a form even in an instant. Is it entirely ephemeral? Or does one lick of a flame definitely exist, if just for a second?
All of life is a fire. Nothing stays the same, although some licks move so slowly, it looks as though they are permanent structures. Mount Everest, though, is an object in motion. It rises up, and it will sink down. Nothing is certain, except in the instant.
