Signpost Quote?

Sorry, this is driving me crazy and I don't know where to find it.
Somewhere in the game, I remember reading the quote that reads somewhere along the lines of "if you hold onto your sense of adventure, you will find your way out / escape".
Does anyone know what I'm talking about and if so, what was the full quote?

thanks

 

It's from the chest where you get the Map System

Something's written here...

So long as you retain your spirit
of exploration, surely you shall
find your way out. This I believe.

 

Damn, thanks a bunch!
