Everyone on His Level

The Yismach Yisroel quotes Rav Yitzchok of Vorka zy”a as explaining that the Torah is telling everyone to serve Hashem on their own level, and not to try to jump to a level that is above them. It says to “be holy” as you are, maintaining the level of kedusha that you currently are on, and not to try to push ahead to a level you have yet to attain. This is as tzadikim say: “You cannot fall from the ground”, meaning that if you don’t try to climb higher than you are able to climb, you will not have a downfall.
