It’s the same old wilderness,

just no longer up on that hill or around that bend or in the gully. It’s the fact that there is no more hill or gully, that the hollow is there and you’ve got to explore the hollow with faith. 
If you don’t have faith that there is something down there, pretty soon when you’re in the hollow, you begin to get scared and start shaking. That’s when you stop taking acid and start taking coke and drinking booze and start trying to fill the hollow with depressants and Valium. 
Real warriors like William Burroughs or Leonard Cohen or Wallace Stevens examine the hollow as well as anybody; they get in there, look far into the dark, and yet come out with poetry.
