Madonna Kabbalah - Guy Ritchie's next movie

Ritchie's latest film project, The 49th Gate, is a drama about people trapped between heaven and hell, inspired by the writings of the Kabbalah. The key principle involved in his screenplay is that there are 50 levels of holiness for a person to attempt to reach, but the 50th is close to impossible. Even Moses failed to attain it.

Madonna Kabbalah - what is the difference between catholicism and kabbbalah?

"Guy Ritchie always says, 'The difference between Kabbalah and Catholicism is the amount of people,' " says Berg, sitting in an office at the center's New York branch. A Madonna biography stands in the bookshelf behind him. "You don't call Catholicism a cult."

And if Madonna's outreach efforts find continued success, Berg says, the critics will be quieted.

"Eventually, when there's enough people doing Kabbalah" — when there are as many people wearing Red Strings as crosses — "it won't even be an issue."
