The twenty-first head of the Moon sphere instructs the magician how, by certain magic and quabbalistic methods, to become strong and resistant against any visible and invisible enemies, against any kind of influence by elements, etc. He becomes magically taboo. No man on earth is able to assail or do harm to a magician who enjoys - and works under - the pro- tection and guidance of this head of the Moon sphere. The magi- cian is safe from any persecution or magical assault. He is capable of enduring the greatest possible heat, of going through the greatest fire, without a single hair of his head being burned. By following special methods revealed to him by this head the magi- cian can make his body as hard as a diamond. He is invulnerable from the magical point of view and master over his life and death.
