Where there’s a beginning, there’s an ending, and vice versa. But where neither exists is where everything infinite resides.
And even though he knows this song definitely has a first and a last note, he feels as if he’s been singing it forever; that the whole universe has been singing forever and he’s only just discovered it out of something more than coincidence or luck. He feels that if he could split a grain of sand in half, it would burst into the tune of this very song, and find that he will have nowhere to go because he’d be exactly where he should be at that very moment.
He’d be in a place where no one and nothing can separate, because he’d never be able to be lost again.
Where there’s a beginning, there’s an ending, but the song he sings is one where the beginning and ending last longer than eternity.
