Most of us are commonly familar with the idea of black and white magick, white magick seen obviously as being good magick or posistive energy used to help others, and to heal. While black magick is seen as negative energy and is used for cause harm and do destruction and has an assocation with evil.
Though I am of the school of thought that there really is no true thing as black and white magick, all magick comes from energy, and energy in its natural and normal state, when not imposed upon by anything or altared is completely neutral, energy in itself is not black nor white.
It is not the maigck that is truly back or white, but it is in the intent of the person who uses, it is what the indivual does with the eneergy that can make it black or white, but before hand it is completely neutral.
There is no like speical "black magick" or "white magick" for a person to tap into, it all comes from the same source, the same energy, but the will of the person then taints it or purifies it to make magick become black or white.
