WWW- SEXY starlet Jenna Elfman has gotten so deeply into Scientology that her main goal these days is to help it take over the world.

Scientology “is a complete understanding of what is happening on the planet right now,” Elfman, best known for her role on “Dharma & Greg,” told Scientology magazine Celebrity. She boasts that she’s on the second-to-last “Operating Thetan” or “OT” level in the organization’s hierarchy.

Elfman says you must devote yourself to Scientology or “you could be dead.” Fellow celeb Scientologists include Tom Cruise, John Travolta and Lisa Marie Presley.

Scientologists who reach “OT 3” are told about “Xenu,” a galactic ruler who paralyzed humans and sent them back to Earth in spaceships 75 million years ago, reports CultNews.com, which closely follows the faith. They were then arranged around a volcano and murdered with H-bombs, but their souls are still hanging around and are known as “Body Thetans” or “BTs.”

Scientology devotees pay big bucks to “clear” themselves of the BTs’ negative influence through a series of costly courses. Elfman tells the magazine her “duty” is now to help “clear the planet.” She declares, “I intend to make Scientology as accessible to as many people as I can, and that is my goal.”

Elfman’s career hasn’t exactly taken off like Xenu’s spaceship, however. Since “Dharma & Greg” was canceled, she’s appeared in a series of flops. This she seems to attribute to what Scientologists call “Suppressive People” or “SPs.”

“The more successful I became, the more suppression I bumped into,” Elfman says. “Especially in the entertainment industry, which is really home to rabid suppression . . . I don’t have time as a leader, as an OT and as an artist to be suppressed.

“[If] you want to survive as an artist or leader . . . know you are going to be under attack,” Elfman warns. “You have to be able and willing to confront evil if you want to survive.”

Elfman says she has done this by “cleaning house of those people who were very good at convincing [me] that they were there to help, when they were absolutely not . . . Now that I’m willing to confront them, they scurry away” – much like her fans, apparently, and perhaps her publicist, since she no longer has one.

Elfman’s agency, CAA, had no comment on her religious ramblings.
