"In his book Cult Proofing Your Kids, Dr. Paul Martin, a psychologist who directs a recovery center for ex-cultists, observes that the definition of a cult involves far more than simply theological definition:
"(A cult is) .. a group that uses methods that deprive individuals of their ability to make a free choice. They use deceitful recruitment techniques, they deceptively and destructively use the devotees' energies, and they capture the devotee's minds .. to advance the goals of the group leaders to the actual or possible detriment of members, their families, or the community. .. Cults can include groups and organizations that are not typically viewed as cults"."
