Demonology
Demonology is the study of demons or beliefs about demons. They may be human, or nonhuman, separable souls, or discarnate spirits which have never inhabited a body. A sharp distinction is often drawn between these two classes, notably by the Melanesians, several African groups, and others. The Islamic jinn, for example, are not reducible to modified human souls. At the same time these classes are frequently conceived as producing identical results, e.g. diseases.
Prevalence of demons
According to some societies, all the affairs of the universe are supposed to be under the control of spirits, each ruling a certain "element" or even object, and themselves in subjection to a greater spirit. For example, the Inuit are said to believe in spirits of the sea, earth and sky, the winds, the clouds and everything in nature. Every cove of the seashore, every point, every island and prominent rock has its guardian spirit. All are potentially of the malignant type, to be propitiated by an appeal to knowledge of the supernatural. Traditional Korean belief posits countless demons inhabit the natural world; they fill household objects and are present in all locations. By the thousands they accompany travelers, seeking them out from their places in the elements.Greek philosophers such as Porphyry, who claimed influence from Platonism, and the fathers of the Christian Church, held that the world was pervaded with spirits, the latter of whom advanced the belief that demons received the worship directed at pagan gods.
Character of the spiritual world
The ascription of malevolence to the world of spirits is by no means universal. In Central Africa, the Mpongwe believe in local spirits, just as do the Inuit; but they are regarded as inoffensive in the main. Passers-by must make some trifling offering as they near the spirits' place of abode; but it is only occasionally mischievous acts, such as the throwing down of a tree on a passer-by, are, in the view of the natives, perpetuated by the class of spirits known as Ombuiri.So too many of the spirits, especially concerned with the operations of nature, are conceived as neutral or even benevolent; the European peasant fears the corn-spirit only when he irritates him by trenching on his domain and taking his property by cutting the corn; similarly, there is no reason why the more insignificant personages of the pantheon should be conceived as malevolent, and we find that the Petara of the Dyaks are far from indiscriminate and malignant, being viewed as invisible guardians of mankind.
Types
Demons are generally classified as spirits which are believed to enter into relations with the human race. As such the term includes:- angels in the Christian tradition that fell from grace,
- malevolent genii or familiars,
- such as receive a cult,
- ghosts or other malevolent revenants.
Ancient Mesopotamian religion
The ancient Mesopotamians believed that the underworld was home to many demons, which are sometimes referred to as "offspring of arali". These demons could sometimes leave the underworld and terrorize mortals on earth. One class of demons that were believed to reside in the underworld were known as galla; their primary purpose appears to have been to drag unfortunate mortals back to Kur. They are frequently referenced in magical texts, and some texts describe them as being seven in number. Several extant poems describe the galla dragging the god Dumuzid into the underworld. Like other demons, however, galla could also be benevolent and, in a hymn from King Gudea of Lagash, a minor god named Ig-alima is described as "the great galla of Girsu". Demons had no cult in Mesopotamian religious practice since demons "know no food, know no drink, eat no flour offering and drink no libation."Abrahamic religions
Christianity
Christian demonology is the study of demons from a Christian point of view. It is primarily based on the Bible, the exegesis of scriptures, the writings of early Christian philosophers and hermits, tradition, and legends incorporated from other beliefs.Some scholars suggest the origins of early Greek Old Testament demonology can be traced to two distinctive and often competing mythologies of evil – Adamic and Enochic, one of which was tied to the fall of man caused by Adam and Eve in the Garden of Eden and the other to the fall of angels in the antediluvian period. Thus, the Adamic story traces the source of evil to Satan's transgression and the fall of man, a trend reflected in the Books of Adam and Eve which explains the reason for Satan's demotion by his refusal to obey God's command to venerate newly created Adam.
In contrast, the early Enochic tradition bases its understanding of the origin of demons on the story of the fallen Watchers led by Azazel. Scholars believe these two enigmatic figures - Azazel and Satan exercised formative influence on early Jewish demonology. While in the beginning of their conceptual journeys Azazel and Satan are posited as representatives of two distinctive and often rival trends tied to the distinctive etiologies of corruption, in later Jewish and Christian demonological lore both antagonists are able to enter each other's respective stories in new conceptual capacities. In these later traditions Satanael is often depicted as the leader of the fallen angels while his conceptual rival Azazel is portrayed as a seducer of Adam and Eve. While historical Judaism never recognized any set of doctrines about demons, scholars believe its post-exilic concepts of eschatology, angelology, and demonology were influenced by Zoroastrianism. Some, however, believe these concepts were received as part of the Kabbalistic tradition. While many people believe today Lucifer and Satan are different names for the same being, not all scholars subscribe to this view.
A number of authors throughout Christian history have written about demons for a variety of purposes. Theologians like Thomas Aquinas wrote concerning the behaviors of which Christians should be aware, while witchhunters like Heinrich Kramer wrote about how to find and what to do with people they believed were involved with demons. Some texts such as the Lesser Key of Solomon or The Grimoire of Pope Honorius are written with instructions on how to summon demons in the name of God and often were claimed to have been written by individuals respected within the Church. These latter texts were usually more detailed, giving names, ranks, and descriptions of demons individually and categorically. Most Christians commonly reject these texts as either diabolical or fictitious.
In modern times, some demonological texts have been written by Christians, usually in a similar vein of Thomas Aquinas, explaining their effects in the world and how faith may lessen or eliminate damage by them. A few Christian authors, such as Jack Chick and John Todd, write with intentions similar to Kramer, proclaiming that demons and their human agents are active in the world. These claims can stray from mainstream ideology, and may include such beliefs as that Christian rock is a means through which demons influence people.
Not all Christians believe that demons exist in the literal sense. There is the view that the language of exorcism in the New Testament is an example of what was once employed to describe the healings of what would be classified in modern days as epilepsy, mental illness etc.
Islam
Islam has no doctrinal hierarchy of demonology. Even though some Muslim scholars tried to classify jinn and demons, there is no established classification and terms for jinn may overlap or be used interchangeably. Naming the jinn also depends on cultural influences. Julius Wellhausen states, that Islamic demonology is also zoology. Many demonic or demon-like entities are not purely spiritual, but also physical in nature and related to animals. One prominent classification is made by Jahiz:- Angel: a jinni, which is pure and good
- Amir: a jinni, who lives among humans
- Shaitan: a malicious and rebellious jinn
- Marid: a stronger type of jinn, trying to steal information from heaven
- Ifrit: the most powerful type of jinn
- Jinn or Jann: ordinary jinn, a class apart from other jinn types, but also used as a collective to refer to invisible beings in general
- Shaitan: Malevolent jinni, who causes illness and madness
- Ifrit: delimitation to ordinary jinn remains unclear. Can be either a powerful cunning Jinn or strong Shaitan. Ifrits are generally bad.
- Marid: a haughty and powerful Shaitan or very malevolent Ifrit.
- Bu'Bu: a jinn that frightens children.
- Si'lah: a female demon who seduces men.
- Amir: spirits dwelling in houses.
- Ghul: generally evil, lives in the desert.
- Qarînah: name for a specific demon strangling children.
- Hatif: a mysterious phenomenon, which can only be heard but never seen.
Additionally the Peri and the Daeva are kinds of Jinn in Persian lore. While the Daeva are akin to the Shayateen, subordinates of Satan, the Peris are good Jinn fighting the Daeva. However the Peri may endanger people, if they become angered.
Ahmad al-Buni relates four Ifrits to archdemons, diametric opposites to the four archangels of Islam. They have their own Shayātīn under command, and are subordinate to Iblis, who is thought to be the leader of Shayātīn.
Judaism
does not have a demonology or any set of doctrines about demons.Use of the name "Lucifer" stems from, a passage which does speak of the defeat of a particular Babylonian King, to whom it gives a title which refers to what in English is called the Day Star or Morning Star.
There is more than one instance in Jewish medieval myth and lore where demons are said to have come to be, as seen by the Grigori angels, of Lilith leaving Adam, of demons such as vampires, unrest spirits in Jewish folklore such as the dybbuk.
Indian religions
Buddhism
Traditionally, Buddhism affirms the existence of hells peopled by demons who torment sinners and tempt mortals to sin, or who seek to thwart their enlightenment, with a demon named Mara as chief tempter, "prince of darkness," or "Evil One" in Sanskrit sources.The followers of Mara were also called mara, the devils, and are frequently cited as a cause of disease or representations of mental obstructions.
The mara became fully assimilated into the Chinese worldview, and were called mo.
The idea of the imminent decline and collapse of the Buddhist religion amid a "great cacophony of demonic influences" was already a significant component of Buddhism when it reached China in the first century A.D., according to Michel Strickmann. Demonic forces had attained enormous power in the world. For some writers of the time this state of affairs had been ordained to serve the higher purpose of effecting a "preliminary cleansing" that would purge and purify humanity in preparation for an ultimate, messianic renewal.
Medieval Chinese Buddhist demonology was heavily influenced by Indian Buddhism. Indian demonology is also fully and systematically described in written sources, though during Buddhism's centuries of direct influence in China, "Chinese demonology was whipped into respectable shape," with a number of Indian demons finding permanent niches even in Taoist ritual texts.
Also, the Śūraṅgama Sūtra, a major Mahayana Buddhist text, describes fifty demonic states: the so-called fifty skandha maras, which are "negative" mirror-like reflections of or deviations from correct samādhi states. In this context demons are considered by Buddhists to be beings possessing some supernatural powers, who, in the past, might have practiced Dharma, the Buddha's teaching, but due to practicing it incorrectly failed to develop true wisdom and true compassion, which are inseparable attributes of an enlightened being such as a Buddha or a Bodhisattva. In his autobiography, The Blazing Splendor, Tulku Urgyen Rinpoche, a prominent Tibetan Buddhist master of the 20th century describes encounters with such beings. Therefore, depending on the context, in Buddhism demons may refer to both disturbed mind states and actual beings.
