The Threefold Law
Here is an article on why black magick is generally not effected by the Threefold Law, often called the Rule of Return. The threefold law, states that what you do will return to you three times. This is also known as the law of Return, which is a law imposed upon the practitioners of Wiccan magick.
This creed, written for the Wiccan path, wasn't even published until
the 1970's by Wicca author and leader, Gwen Tompson. It is called the Witches Creed,
and it's rule of law states;
Generally the belief is held that what one does with magick will return to them, threefold. This type of thinking is definitely dangerous and unnecessary when working with Black magics. This type of sentiment, creates the belief that black magick is harmful to the caster and the spell will return to the magician with harmful effects.
Here are some useful points to remember when working with black magick. As a general definition: Black magick uses the force of entropy to break down or dissolve: White (wiccan-types) or healing magics use the force of chi, life energy to sustain and heal. In comparison, Black magick is a force of destruction, and entropy.
Entropy and it's Natural Effects
As noted in science, physics, etc. anything that exists physically will eventually break
down, die, or dissolve. Anything that is composed of energy will eventually loose that
energy through the natural process of destruction. This force of destruction is therefore,
a natural process, and the black magician is the conductor of this energy.
The mage gives the energy a place to go (a target) and a reason to begin destruction. The mage, through intent and will, forces these energies on the victim through many various means of magick. The magician is not the target of spells that are cast on others.
Just as the White magican does not experience effects of return from their spells, neither does the black magician who focuses the spell on the target, with singular focus.
The energy that is sent, should be singular in focus without even the thought that it will return. Wasting mental energies on thoughts of return will only complicate life and give skewed results. It is only a process that is set into motion by the magician, a process that facilitates the mental and physical breakdown of the victim. Thus, the magician is not the target of the energies, the victim is.
However, as with all paths, some sort of personal maintenance must be a part of the magicians routine. While the caster is using these energies, a residual effect from negative, black or dark energies, can take hold within the mind, (effect the aura) and effect the physical and mental performance.
It is recommended to find a meditation practice, chakra work, meditation with stones and crystals, or any other activity that brings you rest and balance. This will enable you to grow stronger in time as you "shed away" the things you no longer need with these meditative practices. Self-diagnosis of your own personal spiritual needs have to be addressed in order for you to learn and survive while on the path.
