John Travolta on Monday said he's "saved lives" with Scientology -- including his own "several times."
The Pulp Fiction star, appearing on Good Morning America to promote his upcoming film The Forger, was asked about the controversy surrounding the HBO documentary Going Clear: Scientology and the Prison of Belief.
"People really need to take the time and read a book -- that's my advice," he said, suggesting people read founder L. Ron Hubbard's books Scientology: A New Slant On Life or Dianetics.
"I think if you really read it," the Grease star said, "you'll understand it."
He said of the recent backlash against his faith: "Sometimes, when something really works well, it becomes a target.
"I think for me, 40 years now I've been a part of it and I loved every minute of it," the actor said.

The Hairspray star noted that his "family has done so well with" Scientology, as well.
"And here I am, talking to you because of it."
The Forger opens in theaters Friday.
