A man is uncertain and troubled with his future prospect. He cannot think his way out of it with the cloud in his mind. He seek a holy man for help. This holy man through prayer and belief, invoke God's blessing upon the man. The troubled man believed and felt peace descend upon him. He does not have a solution to his problem at hand, but he is now instilled with peace and belief that God's will assist him through it. He left with this feeling. The holy man, on the other hand, felt that he helped the man and better the world a little. So both men parted ways feeling a little better.
I, personally will not be so convinced. But I see a little good there.
** Yes, there are con men using this trick too, but that itself can be another topic.
