In the Parable of the Rich Man and His Poor Son the son and the father are disconnected from each other. The son does not realize connection is possible and so does not seek it. The father though, does realize alienation or disconnection or separation from his son. The alienation becomes most strong when the poor son is directly confronted by the great wealth of the father. We may find this occurs in our own lives, we may feel most distant from enlightenment when we compare our lives to the lives of others.
In a way comparisons are a form of ensuring alienation endures.
