'Black' is a relatively short e-book about the dark side of the Kaballah and magic which is written as a book and a mystical resource for the Qultura community and for other people who might be interested. As Qultura is based on the Kaballah (as well as aspects of eastern cosmology) it's relevant to anyone with an interest in Qultura.
It's not an in-depth analysis but covers the major areas of what is known as 'the other side' and the dark side of the Kaballah and magic.
Hopefully it gives you a clear insight into dark matters.
