I understood the life around me better, not from love, which everybody acknowledges to be a great teacher, but from estrangement, to which nobody has attributed the power of reinforcing insight

The ending can only start with the beginning and end with self estrangement, as to become once again his own/old self. This is why every man is a continuous ending.

The more he identifies with the dominant images of need, the less he understands his own life and his own desires. The spectacle's estrangement from the acting subject is expressed by the fact that the individual's gestures are no longer his own; they are the gestures of someone else who represents them to him.

To pass from estrangement from God to be a son of God is the basic fact of conversion. That altered relationship with God gives you an altered relationship with yourself with your brother man with nature with the universe.
