“The black magician thinks that through rituals, talismans, and force of personal will that he/she can actually gain control over elemental spirits and the Jinn, and direct them to act in accord with his/her beckoning. Since demons want to feed on the valuable shells of these magicians when they break up at death, in order to get the power to incarnate physically themselves or gain access to deeper hells, they go along with the game. Hence, the Jinn are often quite willing to give the sorcerers low level occult powers, coveted material prizes, or apparent control over elemental spirits, which the demons see as having little value compared to the vital energy of the shells they seek to gain.
The Left-Handed Path is very rapid because of the intense focus of the mind in hatred for God-as-Adversary. This path can therefore yield some results in a relatively short time, but inevitably ends in the destruction of the sorcerer because he/she cannot withstand the power channeled through their shells from the higher Sefiroth. Most do not make it past the Gate of the Tzade צ between the Sefiroth Power/Fire and Understanding/ North. Very powerful black magicians, who make it up the Column of the Left without shattering their shells, are denied access to Atziluth (World of Emanation) by the action of the Gate of the Ayin ע (“Gate of the Unclean Servants”) between the Sefiroth Understanding/North and Crown/Above. This gate redirects such souls into extinction via the Abyss at the invisible Sefirah Knowledge/First.”
