Mazzy, Seems I saw something about it but not sure if it was on Oprah or another talk show.. I remember the one panelist was the spiritual pastor of the church in the L.A. area that Iyanla sent Jill to..
I think his name is Michael Beckwith.
I just did a search on 'the secret' and I guess they are probably in the process of bringing a movie out and the talk show circuit probably help market the movie.
Here is a website about 'The Secret'..

I remember when I saw the panel, that I looked for Iyanla..as I am under the impression that she is also a follower of this philosophy.
I don't know whether it is a religion per se..
