Enlightenment: The "full comprehension of a situation". It translates several Buddhist terms and concepts, most totably bodhi, kensho and satori. Related terms from Asian religions are moksh (liberation) in Hinduism and Kevala Jnana in Jainism. In Christianity, the word "enlightenment" is rarely used, except to refer to the Age of Enlightenment.
Nirvana: A transcendent state in which there is neither suffering, desire, nor sense of self, and the subject is released from the effects of karma and the cycle of death and rebirth. It represents the final goal of Buddhism.
Scientology: L. Ron Hubbard's successor of Dianetics. Its method of spiritual rehabilitation is auditing, in which practitioners re-experience painful or traumatic events in their past in order to free themselves of their limiting effects. Auditing sessions are available to members on a fee-for-service basis, described as a “fixed donation.” Scientology is often characterized as a cult and it has faced harsh scrutiny for many of its practices which, critics contend, include brainwashing and routinely defrauding its members, and harassing its critics. Scientologists have argued that theirs is a genuine religious movement that has been misrepresented, maligned and persecuted. Controversy has focused on Scientology’s belief that souls reincarnate and have lived on other planets before living on Earth, and that some of the related teachings are not revealed to practitioners until they have paid thousands of dollars to the Church of Scientology. Scientologists believe that psychiatry is destructive.
