The majority of texts attributed to so-called masters, resurrected initiates, and others, are the efforts of black magicians to legitimize their art. This includes any grimoires or spells used to invoke entities, demons, and sorcerers.
Sadly, even the Torah has been adulterated and includes elements of black magic, introduced into the text to mislead the naive and uneducated.
For thirty years I sought God. But when I looked carefully I found that in reality God was the seeker and I the sought. -Bayazid al-Bastami
