The Devil
is the name given to a supernatural entity, who, in most Western religions, is the central embodiment of evil. This entity is commonly referred to by a variety of other names, including Satan, Asmodai, Beelzebub, Lucifer and/or Mephistopheles. In classic demonology, however, each of these alternate names refers to a specific supernatural entity.

Satan frozen at the center of Cocytus, the ninth circle of Hell in Dante\'s Inferno.Some scholars believe that the notion of a central supernatural embodiment of evil, as well as the notion of angels, first arose in Western monotheism when Judaism came into contact with the Persian religion of Zoroastrianism. Much like classical monotheism, Zoroastrianism has one supreme God, and an evil spirit who chose to be evil, engaged in a cosmic struggle where both are more or less evenly matched, though from the beginning Ahura Mazda\'s triumph is foretold; making Zoroastrianism an ethical dualism. Ahura Mazda ("Wise Lord"), also later known as Ormazd in Middle Persian, is the God of light, or Truth, and Angra Mainyu ("Evil Spirit"), also later known as Ahriman in Middle Persian, is the primeval Spirit of darkness, or the Lie. In a final battle between the forces of good and evil, human souls will be judged in a fiery ordeal of molten metal where the good will pass through as if it were warm milk and those who chose evil will be purified and all will be reunited in the new perfected world. Accordingly, humans are urged to align themselves with Ormazd and his Yazatas ("angels") and to shun His adversary who is the ruler of darkness and his demons, so that they may facilitate the final renovation (Frashō-kereti).

Christianity views Satan as an angel cast from heaven by God, for being prideful, deceitful, and the tempter: all strikingly similar to the story of Ahriman.

THE demon
In religion, folklore, and mythology a demon is a supernatural being that has generally been described as a malevolent spirit. A demon is frequently depicted as a force that may be conjured and insecurely controlled. The "good" demon in recent use is largely a literary device (e.g., Maxwell\'s demon). In common language, to "demonize" a person means to cast aspersions on them.

Most scholars acknowledge that Judeo-Christianity owes a great debt to Zoroastrianism in regards to the introduction of angelology and demonology, as well as Satan (Ahriman) as the ultimate agent of evil. As the Iranian Avestan and Vedic traditions as well as other branches of Indo-European mythologies show, the notion of \'demons\' has existed for many centuries.

Ancient Egyptians also believed in demonic monsters that might devour living souls while they traveled towards the afterlife, although demons per se did not exist in Ancient Egyptian belief.

The Greek conception of a daemon (δαίμων daímon) appears in the works of Plato and many other ancient authors, but without the evil connotations which are apparent in the Septuagint translation of the Hebrew Bible and in the Greek originals of the New Testament. The medieval and neo-medieval conception of a "demon" in Western civilization (see the Medieval grimoire called the Ars Goetia) derives seamlessly from the ambient popular culture of Late (Roman) Antiquity: Greco-Roman concepts of daemons that passed into Christian culture are discussed in the entry daemon, though it should be duly noted that the term referred only to a spiritual force, not a malevolent supernatural being. The Hellenistic "daemon" eventually came to include many Semitic and Near Eastern gods as evaluated by Christianity.

The supposed existence of demons is an important concept in many modern religions and occultist traditions. In some present-day cultures, demons are still feared in popular superstition, largely due to their alleged power to possess living creatures.

In the contemporary Western occultist tradition (perhaps epitomized by the work of Aleister Crowley), a demon, such as Choronzon, the "Demon of the Abyss", is a useful metaphor for certain inner psychological processes, though some may also regard it as an objectively real phenomenon.

Goetia


Goetia refers to a practice which includes the Invocation or Evocation of demons, and largely derives from the 17th century grimoire Lemegeton Clavicula Salomonis, or The Lesser Key of Solomon

Satan (Standard Hebrew: שָׂטָן, Satan Tiberian Hebrew Śāṭān; Koine Greek: Σατανάς, Satanás; Aramaic: צטנא, Tzaṭanâ; Arabic: +++++, Shaiṭaan) is a term with its origins in the Abrahamic faiths which is traditionally applied to an angel, demon, or minor god in many belief systems.

Satan plays various roles in the Tanakh, the Apocrypha and New Testament. In the Tanakh, Satan is an angel whom God uses to test man for various reasons usually dealing with his level of piety. In the Apocrypha and New Testament, the term Satan refers to a preternatural entity, an evil, rebellious demon who is the enemy of God and mankind, and the central embodiment of evil. Satan is also commonly known as the Devil, the "Prince of Darkness," Beelzebub, Belial, Lucifer, and Mephistopheles.

In the Talmud and some Kabbalist works, Satan is sometimes called Samael. In the fields of angelology and demonology these different names sometimes refer to a number of different angels and demons, and there is significant disagreement as to whether any of these entities are actually evil.

In Islam, Iblīs (Arabic +++++), is the primary devil. He is commonly referred to in the Qur\'an as Shaitan. The Islamic view of Satan has both commonalities and differences with Christian and Jewish views
