“Great things are done when men and mountains meet.”
It isn't the mountains ahead to climb that wear you out; it's the pebble in your shoe.
It's impossible to fall of mountains you fool!
It was the work of the quiet mountains, this torrent of purity at my feet.
You won't find reasonable men on the tops of tall mountains.
On the mountains of truth you can never climb in vain: either you will reach a point higher up today, or you will be training your powers so that you will be able to climb higher tomorrow.
Men do not stumble over mountains, but over molehills.
