“To be sure, some maggidim were messianic, fulminating orators of the fire-and-brimstone school, fundamentalists who hammered away at sin and its fearful punishment, like the revivalists of the American 'Bible belt.' But the most beloved maggidim were the homey philosopher types—good-natured, humane, tolerant of human frailty, skillful in mixing jokes, stories, and parables into their sermons." (NJY)
"The most famous maggid was the one who spoke regularly to Rabbi Yosef Caro (1488-1575) the author the Shulchan Aruch, the Code of Jewish Law. As a rule, the maggid would appear to him early on Shabbat morning after Caro had studied several chapters of Mishnah." (source)
