"It's a big mitzvah to be happy all the time"
-Rabbi Nachman of Breslav
And juggling can help provide this mitzvah to spectators since people invariably enjoy juggling acts. We, in turn, get joy from showing off our talents and making money from our hobby.
Below are some Jewish occasions and Simachot (joyous occasions) specifically appropriate for merrymaking in the form of a juggling performance:
Purim- Jewish holiday celebrating the victory of the Jews of Persia over the wicked Haman. The holiday is celebrated with great joy, costumes, and dancing.
Weddings- At a Jewish wedding, it is considered an obligation for guests to make the bride and groom happy. After some dancing, the bride and groom are seated and the guests amuse them with dancing, juggling, and general merrymaking. See the wedding scene in Fiddler on the Roof an example of bottle dancers entertaining.
Bar Mitzvahs- Another happy occasion where jugglers are often present.
