“On retreats, sittings run between thirty and sixty minutes—most are forty-five—and the regular sittings that we have here in Cambridge last for an hour. The amount of time is less important than the regularity. It is good to sit a little longer than you want to so you see the part of your mind that resists practice, but you don’t want to torture yourself.” – Larry Rosenberg, Breath by Breath (Shambhala, 1998)
