Not all insights spring from experience of the outer world, as did Fushek’s and Dryden’s; some stem from deep self-reflection. Rabbi Zalman Schachter-Shalomi is a preeminent rabbi and teacher. He is professor emeritus at Temple University, and is well known for his work to ecumenize Western religion. Nearing the age of sixty, Reb Zalman felt ‘‘ anxious and out of sorts’’ whenever he was alone, realizing that he was growing old. He had many unanswered questions about what to do with his later years. He went on a forty-day retreat in a rustic cabin in the Southwest to pray, meditate, write, and study. He also took many long walks. During his retreat Rabbi Zalman began ‘‘harvesting his life’’— enjoying his past contributions and asking what legacy he wanted to leave. He asked himself, ‘‘If I had to die now, what would I most regret not having done? What remains incomplete in my life?’’ He recognized these questions as those that might be, and perhaps ought to be, asked and answered by anyone his age who wished to pursue a new vision of their later years. One result of Reb Zalman’s insight is the Spiritual Eldering Institute that ‘‘envisions a society in which elders make a difference as active contributors in their families and communities, and in the healing of our planet.’’
