Spirit (supernatural entity) in the context of "Demons"

In the practice of religion, a cult image is a human-made object that is venerated or worshipped for the deity, spirit or daemon that it embodies or represents. In several traditions, including the ancient religions of Egypt, Greece and Rome, and Hinduism, cult images in a temple may undergo a daily routine of being washed, dressed, and having food left for them. Processions outside the temple on special feast days are often a feature. Religious images cover a wider range of all types of images made with a religious purpose, subject, or connection. In many contexts "cult image" specifically means the most important image in a temple, kept in an inner space, as opposed to what may be many other images decorating the temple.

The term idol is an image or representation of a god used as an object of worship, while idolatry is the worship of an "idol" as though it were God.

An angel is a spiritual heavenly, or supernatural entity, usually humanoid with bird-like wings, often depicted as a messenger or intermediary between God (the transcendent) and humanity (the profane) in various traditions like the Abrahamic religions. Other roles include protectors and guides for humans, such as guardian angels and servants of God. In Western belief-systems the term is often used to distinguish benevolent from malevolent intermediary beings.

Emphasizing the distance between God and mankind, revelation-based belief-systems require angels to bridge the gap between the earthly and the transcendent realm. Angels play a lesser role in monistic belief-systems, since the gap is non-existent. However, angelic beings might be conceived as aid to achieve a proper relationship with the divine.

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.

In folklore, a ghost is the soul or spirit of a dead person or non-human animal that is believed by some people to be able to appear to the living. In ghostlore, descriptions of ghosts vary widely, from an invisible presence to translucent or barely visible wispy shapes to realistic, lifelike forms. The deliberate attempt to contact the spirit of a deceased person is known as necromancy, or in spiritism as a séance. Other terms associated with it are apparition, haunt, haint, phantom, poltergeist, shade, specter, spirit, spook, wraith, demon, and ghoul.

The belief in the existence of an afterlife, as well as manifestations of the spirits of the dead, is widespread, dating back to animism or ancestor worship in pre-literate cultures. Certain religious practices—funeral rites, exorcisms, and some practices of spiritualism and ritual magic—are specifically designed to rest the spirits of the dead. Ghosts are generally described as solitary, human-like essences, though stories of ghostly armies and the ghosts of animals other than humans have also been recounted. They are believed to haunt particular locations, objects, or people they were associated with in life. According to a 2009 study by the Pew Research Center, 18% of Americans say they have seen a ghost.

A fairy (also called fay, fae, fae folk, fey, fair folk, or faerie) is a type of mythical being or legendary creature, generally described as anthropomorphic, found in the folklore of multiple European cultures (including Celtic, Slavic, Germanic, and French folklore), a form of spirit, often with magical, metaphysical, supernatural, or preternatural qualities.

Myths and stories about fairies do not have a single origin but are rather a collection of folk beliefs from disparate sources. Various folk theories about the origins of fairies include casting them as either demoted angels or demons in a Christian tradition, as deities in pagan belief systems, as spirits of the dead, as prehistoric precursors to humans, or as spirits of nature.

A monster is a type of imaginary or fictional creature found in literature, folklore, mythology, horror, fantasy, fiction and religion. They are very often depicted as dangerous and aggressive, with a strange or grotesque appearance that causes terror and fear, often in humans. Monsters usually resemble bizarre, deformed, otherworldly and/or mutated animals or entirely unique creatures of varying sizes, but may also take a human form, such as mutants, ghosts, spirits, vampires or zombies, among other things. They may or may not have supernatural powers, but are usually capable of killing or causing some form of destruction, threatening the social or moral order of the human world in the process.

Animal monsters are outside the moral order, but sometimes have their origin in some human violation of the moral law (e.g. in the Greek myth, Minos does not sacrifice to Poseidon the white bull which the god sent him, so as punishment Poseidon makes Minos' wife, Pasiphaë, fall in love with the bull. She copulates with the beast, and gives birth to the man with a bull's head, the Minotaur). Human monsters are those who by birth were never fully human (Medusa and her Gorgon sisters) or who through some supernatural or unnatural act lost their humanity (werewolves, Frankenstein's monster), and so who can no longer, or who never could, follow the moral law of human society.

Evocation is the act of evoking, calling upon, or summoning a spirit, demon, deity or other supernatural agents, in the Western mystery tradition. Conjuration also refers to a summoning, often by the use of a magical spell. The conjuration of the ghosts or spirits of the dead for the purpose of divination is called necromancy. Comparable practices exist in many religions and magical traditions and may employ the use of mind-altering substances with and without uttered word formulas.

Shamanism is a spiritual practice that involves a practitioner (shaman) interacting with the spirit world through altered states of consciousness, such as trance. The goal of this is usually to direct spirits or spiritual energies into the physical world for the purpose of healing, divination, or to aid human beings in some other way.

Beliefs and practices categorized as shamanic have attracted the interest of scholars from a variety of disciplines, including anthropologists, archeologists, historians, religious studies scholars, philosophers, and psychologists. Hundreds of books and academic papers on the subject have been produced, with a peer-reviewed academic journal being devoted to the study of shamanism.
