Buber isn't suggesting that loneliness automatically makes us better people—a trap many spiritual seekers fall into. Rather, he's identifying solitude as an *active practice*, a deliberate withdrawal where we strip away the social masks and performed versions of ourselves we wear in company. When you sit alone with a difficult truth about yourself—say, recognizing that you've been unkind out of insecurity—that moment of reckoning without audience is where real change begins. The purification happens not through isolation itself, but through the honest conversation you finally have with yourself when there's no one else to perform for.
