“[T]he Dalai Lama often talks about sleep as one of the most important activities of the day, even calling on old texts to suggest how sleep can in fact be positively used, as almost anything can, for the clarification of the mind. It appeals to him, I think, because it is one activity that every member of humanity has in common, and the nature of our sleep plays a large part in how clearly we see the world.”

—Pico Iyer, The Open Road: The Global Journey of the Fourteenth Dalai Lama, 2008.
