"The things that can restore us have to get in, too. This is what the wisdom of an open heart is all about. All the spiritual traditions speak of this but I love the Tibetan tradition: "A spiritual warrior always has a crack in his heart because that is how the mysteries can get in.""

Some form of suffering often brings about a readiness. One can say it cracks open the shell of the egoic mind with which many people identify as "me." Life cracks open that shell, and once that crack is there, then we are reached more easily by spiritual teaching.
