Consider for a moment the possibility that sin might refer to all actions and attitudes that lead people to become alienated from their most whole and holy self. In other words, the notion that sin is that which separates us from God can be understood as those actions and attitudes that separate us from our own true being. If so, teshuvah can then be understood as the process whereby we restore or return to our most natural state of inner wholeness and self-integration.
