Spirit possession in the context of "Coast Veddas"

A demon is a malevolent supernatural entity. Historically, belief in demons, or stories about demons, occurs in folklore, mythology, religion, occultism, and literature; these beliefs are reflected in media includingfiction, comics, film, television, and video games. Belief in demons probably goes back to the Paleolithic age, stemming from humanity's fear of the unknown, the strange and the horrific. In ancient Near Eastern religions and in the Abrahamic religions, including early Judaism and ancient-medieval Christian demonology, a demon is considered a harmful spiritual entity that may cause demonic possession, calling for an exorcism. Large portions of Jewish demonology, a key influence on Christianity and Islam, originated from a later form of Zoroastrianism, and was transferred to Judaism during the Persian era.

Demons may or may not be considered to be devils: minions of the Devil. In many traditions, demons are independent operators, with different demons causing different types of evils (destructive natural phenomena, specific diseases, etc.) in general, while devils appear more often as demons within a theologial framework; demons opposing the Divine principle. As lesser spirits doing the Devil's work, they have additional duties— causing humans to have sinful thoughts and tempting humans to commit sinful actions.

Judas Iscariot (/ˈdʒuːdəs ɪˈskæriət/; Biblical Greek: Ἰούδας Ἰσκαριώτης, romanized: Ioúdas Iskariṓtēs; c. 3 AD – c. 30 to 33 AD) was, according to Christianity's four canonical gospels, one of the original Twelve Apostles of Jesus Christ. Judas betrayed Jesus to the Sanhedrin in the Garden of Gethsemane, in exchange for thirty pieces of silver, by kissing him on the cheek and addressing him as "master" to reveal his identity in the darkness to the crowd who had come to arrest him. In modern times, his name is often used synonymously with betrayal or treason.

The Gospel of Mark gives no motive for Judas's betrayal but does present Jesus's predicting it at the Last Supper, an event also described in all the other gospels. The Gospel of Matthew 26:15 states that Judas committed the betrayal in exchange for thirty pieces of silver. The Gospel of Luke 22:3 and the Gospel of John 13:2 and 13:27 suggest that he was possessed by Satan. According to Matthew 27:1–10, after learning that Jesus was to be crucified, Judas attempted to return the money he had been paid for his betrayal to the chief priests and hanged himself. The priests used the money to buy a field to bury strangers in, which was called the "Field of Blood" because it had been bought with blood money. Acts of the Apostles 1:18 quotes Peter as saying that Judas used the money to buy the field himself, and he "[fell] headlong ... burst asunder in the midst, and all his bowels gushed out." His place among the Twelve Apostles was later filled by Matthias.

Invocation is the act of calling upon a deity, spirit, or supernatural force, typically through prayer, ritual, or spoken formula, to seek guidance, assistance, or presence. It is a practice found in numerous religious, spiritual, and esoteric traditions, where it serves to establish a connection between the human and the divine or metaphysical realms. Invocation can be directed toward a singular deity, multiple deities, spirits, or abstract forces, and may involve formal liturgies, spontaneous prayers, chants, or symbolic actions. Unlike evocation, which is generally understood as calling a spirit to appear outside the practitioner, invocation often implies inviting the entity to be present within or to closely align with the practitioner.

The purpose of invocation varies across cultural and religious contexts. In many traditions, it is used to request divine intervention, protection, wisdom, or blessings in personal or communal matters. Invocation may also serve to consecrate a space, mark the beginning of a sacred ritual, or facilitate a deeper spiritual experience. In mystical or esoteric practices, invocation can be a means of aligning oneself with a higher spiritual principle or archetype, fostering personal transformation or enlightenment. In some traditions, the practitioner ritually identifies with the deity or spiritual figure. This is distinct from possession, where the invoked being is believed to inhabit or act through the practitioner directly and autonomously.

Trance is a state of semi-consciousness in which a person is not self-aware and is either altogether unresponsive to external stimuli (but nevertheless capable of pursuing and realizing an aim) or is selectively responsive in following the directions of the person (if any) who has induced the trance. Trance states may occur involuntarily and unbidden.

The term trance may be associated with hypnosis, spirit possession, magic, flow, prayer, psychedelic drugs, and altered states of consciousness.

Korean shamanism, also known as musok (Korean: 무속; Hanja: 巫俗), is a religion from Korea. Scholars of religion classify it as a folk religion and sometimes regard it as one facet of a broader Korean vernacular religion distinct from Buddhism, Daoism, and Confucianism. There is no central authority in control of musok, with much diversity of belief and practice evident among practitioners.

A polytheistic religion, musok revolves around deities and ancestral spirits. Central to the tradition are ritual specialists, the majority of them female, called mudang (무당; 巫堂). In English they have sometimes been called "shamans", although the accuracy of this term is debated among anthropologists. The mudang serve as mediators between paying clients and the supernatural world, employing divination to determine the cause of their clients' misfortune. They also perform gut rituals, during which they offer food and drink to the gods and spirits or entertain them with storytelling, song, and dance. Gut may take place in a private home or in a guttang shrine, often located on a mountain. The mudang divide into regional sub-types, the largest being the mansin or kangsin-mu, historically dominant in Korea's northern regions, whose rituals involve them being personally possessed by deities or ancestral spirits. Another type is the sesŭp-mu of eastern and southern regions, whose rituals entail spirit mediumship but not possession.
