Chapter 23 of Leviticus describes the annual cycle of Jewish Holy Days. The description culminates with Sukkot, and we are instructed to rejoice and to remember that we dwelt in sukkot, temporary, portable shelters for 40 years as we wandered in the wilderness. But why should dwelling in temporary, fragile shelters be a source of joy? Following Rabbi Lord Jonathan Sacks brilliant commentary, we explore how to nurture joy in the face of our fragile and uncertain futures.
