orteil42:

O Mighty Lord Satan, by whom all things are set free, I cast myself utterly into thine arms and place myself unreservedly under thy all powerful protection. Comfort me and deliver me from all of the hindrances and snares of those who wish to harm me, both seen and unseen.
Visit justice and vengeance upon those who seek my destruction. Render them powerless and devastated. Direct their malice to return upon them tenfold and to destroy them who would resent my being.
Fill my soul with thy invincible power, strengthen me, that I may persevere in my service, and act as an agent of thy works and a vessel of thy will.
This I ask in your name, almighty and ineffable Lord Satan who liveth and reigneth forevermore.
Ave Satanas
