[Avodah] Mitsvat Sukkah is almost unique

[Joseph Kaplan]

REMT Writes: "I have seen it written in the name of the Vilner Gaon  
that the only two mitzvos encompassing the entire body are sukkah and  
yishuv Eretz Yisrael, with which he associated the pasuk "Vayhi  
v'shaleim --sukko um'onaso b'Tziyon."  When I heard R. Riskin quote  
that in a public lecture many years ago, one woman in the audience  
called out:  "what about mikvah?"  R. Riskin then added that to his  
list.
