I am in agreement with Dr. Aquino and the Temple of Set's definition of MAGIC.
BLACK MAGIC
Followers of the Left-Hand Path practice what, in a specific and technical sense, we term Black Magic. Black Magic focuses on self-determined goals. Its formula is "my will be done", as opposed to the White Magic of the Right-Hand Path, whose formula is "thy will be done".
Black Magic is shunned and feared because to do Black Magic is to take full responsibility for one's actions, evolution, and effectiveness.
Since magic enables you to influence or change events in ways neither understood nor anticipated by society, you must develop a sound and sophisticated appreciation for the ethics governing your own motives, decisions, and actions before you put it to use. To use magic for impulsive, trivial, or egoistic desires is not Setian. It must become second-nature to you to carefully pre-evaluate the consequences of what you wish to do, then choose the course of wisdom, justice, and creative improvement.
Magic may either be operative—to cure your mother's illness, get a better job, strengthen your memory, etc.—or illustrative/initiatory. Illustrative/initiatory magical workings seek to enable and enact the lifetime process of Initiation. They are are comparable to "rites of passage" of many primitive cultures and conventional religions, but are distinguished from these in that they represent individually-crafted rather than socially-prescribed change. Initiatory workings thus represent the actualization of self-deification, while social "rites of passage" integrate an individual into society. A "rite of passage" communicating passage into adulthood establishes that the individual involved is now possessed of certain dignity and responsibilities. An initiatory working awakens one to certain individual powers [and responsibilities], which may or may not be used in a social context. Initiation does not occur within a ritual chamber, but it is illustrated there.
Black Magic is the means by which Initiates of the Left-Hand Path experience being gods, rather than praying to imaginary images of gods.
