The Theory & Practice of Black Magic – Manly P Hall
First. The visible universe has an invisible counterpart, the higher planes of which are peopled by good and beautiful spirits; the lower planes, dark and foreboding, are the habitation of evil spirits and demons under the leadership of the Fallen Angel and his ten Princes.
Second. By means of the secret processes of ceremonial magic it is possible to contact these invisible creatures and gain their help in some human undertaking. Good spirits willingly lend their assistance to any worthy enterprise, but the evil spirits serve only those who live to pervert and destroy.
Third. It is possible to make contracts with spirits whereby the magician becomes for a stipulated time the master of an elemental being.
Fourth. True black magic is performed with the aid of a demoniacal spirit, who serves the sorcerer for the length of his earthly life, with the understanding that after death the magician shall become the servant of his own demon.
For this reason a black magician will go to inconceivable ends to prolong his physical life, since there is nothing for him beyond the grave.
The most dangerous form of black magic is the scientific perversion of occult power for the gratification of personal desire. For selfishness is the fundamental cause of all worldly evil. A man will barter his eternal soul for temporal power, and down through the ages a mysterious process has been evolved which actually enables him to make this exchange.
The black arts includes nearly all forms of ceremonial magic, necromancy, witchcraft, sorcery, and vampirism. ☠️
