If there was such a thing as a mind-ectomy or a mind transplant, our guest this week, Sylvia Boorstein, tells us she would have had it, confiding, "I need a mind that doesn't make up worries about something that didn't even happen yet." She calls herself "a life-long worrier, an inveterate fretter." Yet this very same person is an accomplished author, psychotherapist, Buddhist teacher, co-founding teacher at Spirit Rock Meditation Center and a senior teacher at the Insight Meditation Society in Barre, Massachusetts.
