Rabbi Shais Taub leads a discussion covering topics including “Are we replaceable? Why do we go on? In today’s connected society, the problem of disconnectedness, loneliness, and despair have reached epidemic proportion — what can the rebbe’s wisdom teach us about how to find self-worth and a deep sense of well-being?” The lecture, for Chabad of Hackensack, commemorates the 26th yahrzeit of the Lubavitcher rebbe, Rabbi Menachem Mendel Schneersohn. At Chabad of Hackensack and via Zoom. 7:30 p.m. For link: ChabadHackensack.com/3Tammuz or (201) 503-3770.
