Finishing the מאמר, the רבי shows how the י"ג מדות הרחמים are uplifted and infused with עצמות energy when they do their job in expressing the עצמות connection of Hashem and אידן.

This is connected with the חידוש earlier in the מאמר that המלך בשדה is for every איד, even those in the שדה of קליפה.

The מאמר finishes with answering the opening question: אלול includes "ודודי לי" - the י"ג מדות הרחמים, but the point of it all is the "אני לדודי" - the איד's essential oneness with Hashem that is expressed through his עבודה.
