Not long before his death, Henri Nouwen wrote a book called Sabbatical Journeys. He writes about some friends of his who were trapeze artists, called the Flying Roudellas.

They told Nouwen there's a special relationship between flyer and catcher on the trapeze. The flyer is the one that lets go, and the catcher is the one that catches. As the flyer swings high above the crowd on the trapeze, the moment comes when he must let go. He arcs out into the air. His job is to remain as still as possible and wait for the strong hands of the catcher to pluck him from the air.

One of the Flying Roudellas told Nouwen, "The flyer must never try to catch the catcher." The flyer must wait in absolute trust. The catcher will catch him, but he must wait.
