As you ask people these questions each time, you are also directing them to focus that way... so it is suggesting," Rhodes said. "You are encouraging people to close their eyes, to concentrate, and you are not just doing this to regular people but to people who are religiously inclined.

I am saying that it is sad that in an age where we have so much pharmacological advancement we still have people that we cannot help."
