According to Osho, yes: life itself supplies decisive happenings. Every movement has a limit; when you reach the boundary, the circle completes and a natural turning-back—conversion—happens. No one truly returns from the middle; half-experiences regress. Even ‘bad’ fully lived reveals its futility and ripens goodness. The real obstacle is self-deception—believing you are good while you’re not—which postpones change, sometimes for lifetimes.
Life pushes you to the edge of a path; when you really hit the limit, you turn around on your own—unless you fool yourself about who you are.
