Rabbi Chaim Boyarsky spent the week-long Jewish holiday of Sukkot driving his mobile Sukkah from campus to campus in Ottawa. The temporary wood shelter symbolizes life's ephemerality and is typically erected behind homes with the tradition of eating every meal in it. But because of the holiday coinciding with midterms, many students can't fulfill the custom. So, Boyarsky, a rabbi for the Rohr Chabad Student Network of Ottawa, brought the sukkah to them. Some ate their lunch inside the sukkah, and others said a blessing and shook the Lulav and Etrog. The bouquet, made up of willows, a palm branch, etrog (a lemon-like fruit) and myrtles, is shaken during the holiday to represent unity of all kinds of jews, learned, practicing, non-practicing, as each ingredient has a different taste, smell, or none at all.
