Art is like a million different ways of sending a secret message to ourselves to tell us that the house is on fire. We know this intellectually, but the mind tries to minimize the impact. It invents pastimes, habits, wars, gossip, drama, toys and social gatherings to block out the reality of the burning house. It's so hard to wake this mind up.
So that's the message: the house is on fire. You are in a very precarious position. You are really here, and you are really going to die someday. But the worst part isn't the dying; it's the not realizing you're actually alive right now. You're letting it all go by you like it's somebody else's movie and somebody else that's gonna die.
Read the graffiti on the wall. It's written in a thousand different languages, and in a thousand different colors. It's scrawled in blood and dirt and paint by millions of little hands. And it says the same thing over and over: the house is on fire.
