I havent read the entire thread but i'd like to inject some interesting points relevant to the thread
the majority of this thread seems to be about religion and religious healers. The recent derren brown series brings some excellent insight into this and is well worth a watch
this one shows why religion has come about and what are the causes of most religious and supernatural phenomena
This shows that supernatural phenomina can be explained by basic psychology. For example, when you are placed in a room and all sensual stimulus is removed, the brain will create non existent stimulus, which explains most ghost/jinn/poltergeist/whatever stories.
and this video shows the power of the placebo effect, which is widely used by religious healers.
That second video explains the theory behind the healer's setup in the OP - the placebo effect. He has all this religious gubbins around him and makes the setting as spiritual as possible because these will make the healing process more believable to the recipient since they will be deeply religious. Its pretty much the same way as atheists will be more susceptible to the placebo medicine if it is injected compared to pills.
Also, if anyone genuinely had supernatural powers, such as being a fortune teller, being a mystic healer or any of those things mentioned in this thread, i'm pretty sure that they would apply for
James Randi's $1,000,000 challenge. He is willing to give whoever can prove that they have supernatural powers $1,000,000. If someone genuinely had supernatural powers then i'm pretty sure they would apply for this even if they didnt want the money because it would be a massively good gesture to give the money to charity. unsurprisingly no-one has passed even the preliminary tests yet which is pretty good evidence that this kind of stuff is rubbish.
As a final note I would like to say I have nothing against anyone who is religious and I couldn't care less if they believe that the world was sneezed out of the nose of the Great Green Arkleseizure, as long as it makes them happy i'm cool with that. What I do not find acceptable is when people take advantage of religious beliefs to con people or use religion as a reason for violence.
