I love Leonard Cohen. Here's an article from the New York Times about his latest tour.
Asked whether he does yoga to build strength and agility for his stage shows, Mr. Cohen, his demeanor courtly but reserved, smiled and replied, "That is my yoga."
In fact, Mr. Cohen appears to see performance and prayer as aspects of the same larger divine enterprise . . . "There's a similarity in the quality of the daily life" on the road and in the monastery, Mr. Cohen said. "There's just a sense of purpose" in which "a lot of extraneous material is naturally and necessarily discarded," and what is left is a "rigorous and severe" routine in which "the capacity to focus becomes much easier."
