The word “Act” in English has two meanings.
There is the plain meaning, as in “to do”, to perform an action.
Then there is the meaning that is used far more often in our entertainment-centered world, to act as in to be in an actor on the stage or screen, a master thespian.
“How did you do that?”
Rabbi Avigdor Miller ZT”L was a proponent of this second definition of acting in Avodas Hashem. We get caught up in “To thine own self be true.” and being honest to others, even, or especially if it hurts their feelings.
Forget honesty. Act your way through Elul. If it was a totally fake role like playing a zombie, then fake is fake. But when there is some truth to it, like the Jewish capacity to be a Tzaddik, the acting has a real element to it that should be encouraged and fostered.
How did you do all those mitzvos for all those days?
