“Er-Roohánee,” which is universally considered, among the Egyptians, as _true_ magic, is of two kinds, “’ilwee” (or high) and “suflee” (or low); which are also called “rahmánee” (or divine, or, literally, relating to “the Compassionate,” which is an epithet of God) and “sheytánee” (or satanic).—The ’ilwee, or rahmánee, is said to be a science founded on the agency of God, and of his angels, and good genii, and on other lawful mysteries; to be always employed for good purposes, and only attained and practised by men of probity, who, by tradition, or from books, learn the names of those superhuman agents, and invocations which insure compliance with their desires. The writing of charms for good purposes belongs to this branch of magic, and to astrology, and to the science of the mysteries of numbers. The highest attainment in divine magic consists in the knowledge of the “Ism-el-Aazam.” This is “the most great name” of God, which is generally believed, by the learned, to be known to none but prophets and apostles of God. A person acquainted with it can, it is said, by merely uttering it, raise the dead to life, kill the living, transport himself instantly wherever he pleases, and perform any other miracle. Some suppose it to be known to eminent welees.—The suflee is believed to depend on the agency of the devil, and other evil genii; and to be used for bad purposes, and by bad men. To this branch belongs the science called, by the Arabs, “es-sehr;” which is a term they give only to wicked enchantment.—Those who perform what is called “darb el-mendel” (of which I propose to relate some examples) profess to do it by the agency of genii; that is, by the science called er-roohánee: but there is another opinion on this subject which will be presently mentioned.—One of the means by which genii are believed to assist magicians has been explained in the second paragraph of Chapter X. “Es-Seemiya” is generally pronounced, by the learned, to be a false science, and deceptive art, which produces surprising effects by those natural means which have been above mentioned; and the “darb el-mendel,” as perfumes are employed in the performance of it, is considered, by such persons, as pertaining to es-seemiya.
