Going back to your old self after R”H would be like proclaiming Hashem your King, then not doing your duty as His creation. The holidays are like a step by step process for us. -Elul, realize we’re about to proclaim Hashem our King. -R”H Hashem is who we serve. -AYT with Hashem as our King, we better measure up. He decides our fate based on our behavior. -YK is a day to really cleanse ourselves so we can serve our King better. -Sukkos is where we demonstrate our faith in our King. We live in huts simply because He said so.
The Creator of the universe is our King! I hope we can measure up.
