The Divine Presence is the reservoir of the souls of Israel.
It encompasses all souls, regardless of their particular placement, appearance in history, and unique characteristics.
The Divine Presence is the source from which all souls emanate and to which they return.
It is the ocean into which all rivers flow and from which they issue forth.
It follows that when an individual person performs an act of divine service, he thereby draws down divine illumination not only upon his personal being but also upon the essence of the entire congregation of Israel, upon the Jewish nation as a whole.
Rabbi Adin Steinsaltz
