Not for a hundred years!
Seriously, though, every week I attend a "prayer" meeting for a dying friend. Mostly it's just meditation and some songs and letting her know that we love her. I have no way of knowing if it makes her physically better, but it sure helps her spirit. Some days it makes me feel better and sometimes it's the opposite.
It's just that I don't care for people taking credit for the Tao. If I'd the gift to restore life through prayer, I sure wouldn't tell the newspapers.
