Even in science there is a study call paranormal study. Humans should accept that beyond their five senses there are subtle energy that we cant detect.

I suggest TS to look at this

The keyword here is Faith

I believe if you all read the book "The Secret", it also mentioned about Faith, and the power of believe. Also, you people should search up "the law of attraction"

Even in the bible it mentioned
Mark 11:24
Therefore I tell you, whatever you ask for in prayer, believe that you have received it, and it will be yours.

Well i think, a lot of times these "magic" wonderfully might be the work of faith and believe.
