He must reach a very advanced level of meditation, I wont go as far as to say enlightenment, but he is discovering that a way out of this perpetual life/misery cycle exists and he's found it, however there is tremendous fear he finds upon stepping outside his body.
He might realize at the end that the suffereing he thought was inflicted on him from the outside world was actually his own doing all along, and perhaps now he can enter back into his body having experienced a minor awakening to how he ought to navigate through the world and carry himself.
