If enlightenment is the only hope, how to reach it across the soaring wall of hopelessness? Easy-peasy. Walk backward, stop, turn about, dash forward, and jump.

Addendum (December 11, 2016)

Well, it is even easier than that. Much easier, as a matter of fact. Just stop thinking about the wall. Better still, stop thinking altogether. Out of the blue, you will walk through the soaring wall of hopelessness without any trouble. No need to jump, either. Indeed, easy-peasy. Thinking is the only impediment on the road to enlightenment.
