It's an interesting principle expressed here that actually making a commitment to joy is necessary:
As you all know, I have admired Fr. Richard for many years now and was wonderfully privileged to have attended one of his seminars over the 2009 New Year celebration.
I have committed myself to joy. I have come to realize that those who make space for joy, those who prefer nothing to joy, those who desire the utter reality, will most assuredly have it. We must not be afraid to announce it to refugees, slum dwellers, saddened prisoners, angry prophets. Now and then we must even announce it to ourselves. In this prison of now, in this cynical and sophisticated age, someone must believe in joy.
