Boredom is important in meditation practice. It increases the psychological sophistication of the practitioners. They begin to appreciate boredom and they develop their sophistication until the boredom begins to become cool boredom, like a mountain river. It flows and flows and flows, methodically and repetitiously, but it is very cooling, very refreshing.
