Is there any scientific evidence that this stuff works? If not ( I know there isn't ) then what is the point of doing any of this?
Is there any scientific evidence that praying over a rosary will make god answer your prayer? Or that confessing to a priest cleanses you of sin? (Or, many other beliefs based in Christianity.) If not (I know there isn't) then what is the point of doing any of it??
The point is that it brings people closer to their deity, whoever that is. That's good enough for me! And, actually, there are some interesting things going on in the world of science that may link many things metaphysical to the world of science... Read a bit about quantum physics, and it will boggle your mind more than just about anything!!
