Exorcism (from Greek ἐξορκισμός, exorkismos - binding by oath) is the practice of evicting demons or other spiritual entities from a person or an area they are believed to have possessed. Depending on the spiritual beliefs of the exorcist, this may be done by causing the entity to swear an oath, performing an elaborate ritual, or simply by commanding it to depart in the name of a higher power. The practice is ancient and part of the belief system of many cultures and religions.
Requested and performed exorcisms had begun to decline in the Western world by the 18th century and occurred rarely until the latter half of the 20th century when the public saw a sharp rise due to the media attention exorcisms were getting. There was “a 50% increase in the number of exorcisms performed between the early 1960s and the mid-1970s”.
In Catholic Christianity, exorcisms are performed in the name of Jesus Christ. A distinction is made between a formal exorcism, which can only be conducted by a priest during a baptism or with the permission of a Bishop, and "prayers of deliverance" which can be said by anyone.
The Catholic rite for a formal exorcism, called a "Major Exorcism", is given in Section 11 of the Rituale Romanum.  The Ritual lists guidelines for conducting an exorcism, and for determining when a formal exorcism is required. Priests are instructed to carefully determine that the nature of the affliction is not actually a psychological or physical illness before proceeding.
In Catholic practice the person performing the exorcism, known as an exorcist, is a consecrated priest. The exorcist recites prayers according to the rubrics of the rite, and may make use of religious materials such as icons and sacramentals. The exorcist invokes God—specifically the Name of Jesus—as well as members of the Church Triumphant and the Archangel Michael to intervene with the exorcism. According to Catholic understanding, several weekly exorcisms over many years are sometimes required to expel a deeply entrenched demon.
In general, possessed persons are not regarded as evil in themselves, nor wholly responsible for their actions. Therefore, practitioners regard exorcism as a cure and not some kind of punishment. The Catholic rite usually take this into account, ensuring that there is no violence to those possessed, only that they be tied down if deemed necessary for their own protection and that of the practitioners.
Beliefs and practices pertaining to the practice of exorcism are prominently connected with Hindus. Of the four Vedas (holy books of the Hindus), the Atharva Veda is said to contain the secrets related to magic and alchemy. The basic means of exorcism are the mantra and the yajna used in both Vedic and Tantric traditions. Vaishnava traditions also employ a recitation of names of Narasimha and reading scriptures, notably the Bhagavata Purana aloud.
According to Gita Mahatmya of Padma Purana, reading the 3rd, 7th and 9th chapter of Bhagavad Gita and mentally offering the result to departed persons helps them to get released from their ghostly situation. Kirtan, continuous playing of mantras, keeping scriptures and holy pictures of the deities (Shiva, Vishnu, Hanuman, Brahma, Shakti, etc.) (especially of Narasimha) in the house, burning incense offered during a Puja, sprinkling water from holy rivers, and blowing conches used in puja are other effective practices.
A complete description of birth and death and also about the human soul are explained in Katō Upanishad, a part of Yajur Veda. A summary of this is also available as a separate scripture called Kāttakaṃ.
In Islam, exorcism is called ruqya. It is used to repair the damage caused by sihr or black magic. Exorcisms today are part of a wider body of contemporary Islamic alternative medicine called al-Tibb al-Nabawi (Medicine of the Prophet).
Islamic exorcisms consist of the treated person lying down, while a sheikh places a hand on a patient’s head while reciting verses from the Quran. The drinking of holy water (Zamzam Water from Zamzam Well ) may also take place.
Specific verses from the Quran are recited, which glorify God (e.g. The Throne Verse (Arabic: آية الكرسي Ayatul Kursi), and invoke God's help. In some cases, the adhan/"ah-zan" (the call for daily prayers) is also read, as this has the effect of repelling non-angelic unseen beings or the jinn.
Josephus reports exorcisms performed by administering poisonous root extracts and others by making sacrifices. The Dead Sea Scrolls mention that exorcisms were done by the Essene branch of Judaism.
In more recent times, Rabbi Yehuda Fetaya authored the book Minchat Yahuda, which deals extensively with exorcism, his experience with possessed people, and other subjects of Jewish thought. The book is written in Hebrew and was translated into English.
Rabbi Gershon Winkler of New Mexico explains that the procedure for a Jewish exorcism is intended not only to drive away the possessing force, but to help both the possessor and the possessed in an act of healing. The Jewish exorcism ritual is performed by a rabbi who has mastered practical Kabbalah. Also present is a minyan (a group of ten adult males), who gather in a circle around the possessed person. The group recites Psalm 91 three times, and then the rabbi blows a shofar (a ram's horn).
The shofar is blown in a certain way, with various notes and tones, in effect to "shatter the body" so that the possessing force will be shaken loose. After it has been shaken loose, the rabbi begins to communicate with it and ask it questions such as why it is possessing the body of the possessed. The minyan may pray for it and perform a ceremony for it in order to enable it to feel safe, and so that it can leave the person's body.
Demonic possession is not a valid psychiatric or medical diagnosis recognized by either the DSM-IV or the ICD-10. Those who profess a belief in demonic possession have sometimes ascribed to possession the symptoms associated with physical or mental illnesses, such as hysteria, mania, psychosis, Tourette's syndrome, epilepsy, schizophrenia or dissociative identity disorder. In cases of dissociative identity disorder in which the alter personality is questioned as to its identity, 29% are reported to identify themselves as demons. Additionally, there is a form of monomania called demonomania or demonopathy in which the patient believes that he or she is possessed by one or more demons.
The illusion that exorcism works on people experiencing symptoms of possession is attributed by some to placebo effect and the power of suggestion. Some supposedly possessed persons are actually narcissists or are suffering from low self-esteem and act like a "demon possessed person" in order to gain attention.
Psychiatrist M. Scott Peck researched exorcisms and claimed to have conducted two himself. He concluded that the Christian concept of possession was a genuine phenomenon. He derived diagnostic criteria somewhat different from those used by the Roman Catholic Church. He also claimed to see differences in exorcism procedures and progression. After his experiences, and in an effort to get his research validated, he attempted but failed to get the psychiatric community to add the definition of "Evil" to the DSM-IV.
Although Peck's earlier work was met with widespread popular acceptance, his work on the topics of evil and possession generated significant debate and derision. Much was made of his association with (and admiration for) the controversial Malachi Martin, a Roman Catholic priest and a former Jesuit, despite the fact that Peck consistently called Martin a liar and manipulator. Other criticisms leveled against Peck included claims that he had transgressed the boundaries of professional ethics by attempting to persuade his patients to accept Christianity.
For centuries exorcisms have been controversially argued due to the moral beliefs of an individual. Neurosurgical Exorcisms, otherwise known as psychosurgeries, have in the past offered treatments for demonic possessed individuals and later used for intractable mental illnesses. Invented by António Egas Moniz, these surgeries were performed by different neurologist throughout the 1900s and were later termed lobotomies. American neurologist, Walter Freeman, later revolutionized lobotomies with his invention of the ice-pick procedure making it easier for psychosurgeries to be done quicker and at less expense.
Tactics such as these, were introduced as a quest to rid the world of mental illnesses or in past times removal of demons from the soul. These procedures have been deemed unethical, within the public imagination, the terms lobotomy and psychotherapy evoke frightful images of sadistic doctors, zombie patients, mind control, and institutional brutality. For medical professionals, theses terms are reminders of an era with a lack of review boards, uncontrolled clinical trial, and uncodified biomedical ethics. Although practices of lobotomies in majority of the world have disappeared, psychosurgeries have still yet to be abandoned as a last resort therapy for mental illnesses. Opinions have testified exorcisms to be a form of psychotherapy, and psychotherapy to really be a form of exorcism. Psychosurgeries in essence touch on normal emotion, response and functioning as the essence and integrity of the individual.The intuitive objection to the pre-frontal lobotomy was that it permanently and irreversibly affected or diminished normal human functioning of the individual by destroying healthy brain tissue. The outcomes of such procedures being permanent, ethically raise issues with families dealing with the change, the voluntary or involuntary consent of the patient, and the ability of the doctor to make a decision that will generate a benefit rather than a cost to his patient.
- An October 2007 mākutu lifting in the Wellington, New Zealand suburb of Wainuiomata led to the death by drowning of a woman and the hospitalization of a teen. After a long trial, five family members were convicted and sentenced to non-custodial sentences.
- Mother Teresa allegedly underwent an exorcism late in life under the direction of the Archbishop of Calcutta, Henry D'Souza, after he noticed she seemed to be extremely agitated in her sleep and feared she "might be under the attack of the evil one."
- Anneliese Michel was a Catholic woman from Germany who was said to be possessed by six or more demons and subsequently underwent a secret ten-month-long voluntary exorcism in 1975. Two motion pictures, The Exorcism of Emily Rose and Requiem are loosely based on Anneliese's story. The documentary movie Exorcism of Anneliese Michel  (in Polish, with English subtitles) features the original audio tapes from the exorcism. The two priests and her parents were convicted of negligent manslaughter for failing to call a medical doctor to address her eating disorder as she died weighing only 68 pounds. The case has been labelled a misidentification of mental illness, negligence, abuse, and religious hysteria.
- Bobby Jindal, governor of Louisiana, wrote an essay in 1994 about his personal experience of performing an exorcism on an intimate friend named "Susan" while in college.
- Michael Taylor in 1974.
- A boy identified as Robbie Mannheim, was the subject of an exorcism in 1949, which became the chief inspiration for The Exorcist, a horror novel and film written by William Peter Blatty, who heard about the case while he was a student in the class of 1950 at Georgetown University. Robbie was taken into the care of Rev. Luther Miles Schulze, the boy's Lutheran pastor, after psychiatric and medical doctors were unable to explain the disturbing events associated with the teen; the minister then referred the boy to Rev. Edward Hughes, who performed the first exorcism on the teen. The subsequent exorcism was partially performed in both Cottage City, Maryland and Bel-Nor, Missouri by Father William S. Bowdern, S.J., Father Raymond Bishop S.J. and a then Jesuit scholastic Fr. Walter Halloran, S.J.
- Salvador Dalí is reputed to have received an exorcism from Italian friar Gabriele Maria Berardi while he was in France in 1947. Dalí created a sculpture of Christ on the cross that he gave the friar in thanks.
- Clara Germana Cele was a South African school girl who claimed to be possessed in 1906.
- Johann Blumhardt performed the exorcism of Gottliebin Dittus over a two-year period in Möttlingen, Germany from 1842-1844. Pastor Blumhardt's parish subsequently experienced growth marked by confession and healing, which he attributed to the successful exorcism.
- George Lukins in 1778.
