How do you do black magic?

Answer 1

Black Magic is a misnomer, magic has no polarity, it is simply power.

There are two mistaken but common usages for the term "black magic".

-The first is any use of unexplainable energies seen to have "supernatural" basis, and believed by some to "come from the Devil" or be "the Devil's work".

This a religious prejudice, and patently false. Most of the people practicing the Craft are Pagans, followers of any one of a large number of spiritual paths that include magic in their lives. None of them believe in the "Devil", he is an entity of the Abrahamic religions.

-The second is in reference to any "harmful" use of magic.

Witches like everyone else in the world are human and subject to all the good, bad and indifferent motivations of the rest of humankind.

An ethical practitioner spends a large amount of his/her time checking and rechecking the motivation behind their use of magic. We all make mistakes, but at least with an ethical practitioner of magic, you can be certain we take full responsibility for our actions.

Answer 2

I don't know if there are any rules concerning black magic, but maybe you will get an general idea from Wikipedia: "Black magic or dark magic is a form of sorcery that draws on assumed malevolent powers. It may be used for dark purposes or malevolent acts that deliberately cause harm in some way. It is alternatively spelt with a 'k' (magick). This term is also known as the dark arts of magic and dark side magic. In fiction it refers to evil magic. In modern times, people who practice magic use the term to describe power utilised for means of gaining power and wealth or taking revenge. Black magic would be invoked to kill, to steal, to injure, to cause misfortune or destruction, or for personal gain without regard to harmful consequences to others. As a term, "black magic" is normally used to describe a form of ritual that some group or person does not approve of. Not everything that is called black magic truly has malevolent intentions behind it, and some also consider it to have beneficial and benevolent uses, such as killing off diseases or pests (or rather, the effect itself is malevolent by causing death to insects, but as an indirect consequence of black magic, good sometimes results, in the form of less pests around, etc)."
