Succot and Eretz Yisrael

It once occurred to me that there are two positive mitzvot in all the Torah that can be done while sleeping: Succah and Yishuv HaAretz. This was a yearly vort that I would give people until I found it worded slightly differently in the name of the GR"A in the first chapter of Kol HaTor: There are two mitzvot that a person enters in to with their entire body: Succah and Eretz Yisrael. The mitzvah of Succah is that it should be made, and not from what is already made (Aseh v'lo min he'asuy), and thus it is for Tzion (that the building of Tzion/Eretz Yisrael requires doing from Am Yisrael). May we all be zocheh to perform these two mitzvot in their shleimut during the coming Chag!
