Members of the kooky cult recruited Cosby shortly before his 81st birthday on July 12, RadarOnline.com has learned.
"The Scientologists dropped off a book and an odd DVD that we converted to VHS for him to watch," said a Cosby camp insider. "They told him he's an immortal, spiritual being that is a resident in a physical body."
Cult members also gave him a pocket watch and told him he can use it to hypnotize inmates with "subliminal mind control," the insider told Radar.
Now, the "brainwashed" sex fiend is watching the tape daily and practicing the technique on a staff of yes-men — who pretend to be hypnotized.
Cosby's enablers even hatched a scheme to bribe inmates into playing ball.
"His prison 'coach' said the best move is to let him think it works and add money into other prisoners' commissary accounts," said the source.
"That way, he'll get some satisfaction out of this and make our lives easier!"
