Demonic Possession Explained by Carl Jung - Is it Real or Not

Demonic possession traces back to the Abrahamic religions (Judaism, Islam, and Christianity). Take this quote from the New Testament for instance, “And when he came to the other side, to the country of the Gadarenes, two demon-possessed men met him, coming out of the tombs, so fierce that no one could pass that way” (Matthew 8:28).
In the Islamic tradition, demons are often referred to as “Jinn” which are otherworldly creatures who come and cause humanity to sin against Allah. The Quran (holy text of the Islamic people) also speaks about ruqya which is translated as “exorcism” to cast the Jinn out of one’s body.
Discussion about evil and its influence on humanity features a lot in the texts of the Judaic, Islamic, and Christian traditions. Unfortunately, it was this belief in “demonic possession” by external forces that lead to the discrimination, mistreatment and ultimate alienation of what we would refer to in modern times as the mentally ill.
