This painting should be rotated to understand the upside-down world we live in.
One view, an open grave, opens into an infinite dimension of light and beauty. This is where God wants us to "End Up".
Now, rotate the painting in the other direction. We see Man, with a sack of dung for a head, laboring up a dunghill mountain to disappear up Satan's Ass, into the darkness of Hell. It's your choice where you "End Up".
