The cave you fear to enter holds the treasure you seek.
Campbell is really talking about asymmetry—the very thing that terrifies us often signals where we've neglected ourselves most acutely. We don't fear random caves; we fear the ones connected to our actual vulnerabilities, which means the treasure waiting there isn't abstract wisdom but something we desperately need. When someone avoids difficult conversations with a parent, or keeps postponing that creative project, the dread itself is a compass pointing toward what matters most. The insight that cuts deeper than the obvious is this: your fear is not a warning sign to heed but evidence of genuine importance, a map written by your own psyche.
