Marks On My Body After First Banishing Rituals

[Aion]

"The Illustrated Goetia", I'm not surprised. There are some weird pronunciations in there. I would watch out for anything that is based in Goetia since Goetia deals with demonology. Some people have modified the LBRP for such use. Sounds like you tapped in to a current that you didn't mean to.

I would perform again, but in this format:

Qabbalistic Cross

Do not use the dagger, just use your fingers.

Raise hand above head, grasp the light and draw it down to your forehead. Tone "Ateh" AH-TEH (Thou Art)
Bring the light down to the heart and tone 'Malkuth' MAL-KOOT (the Kingdom)
Move to the right shoulder and tone 'Ve Geburah' VEH GEH-BOOR-AH (The Power)
Cross to the left shoulder and tone 'Ve Gedulah' VEH GEH-DOO-LAH (The Glory)
Bring the hands together as in prayer and tone 'Le Olam' LAY OH-LAM (Forever)
Finish toning Amen AH-MEN (Equivalent to 'so mote it be' or 'it is done'.)

Then you will pick up the dagger to perform the LBRP.

You can perform it as it is presented in those pictures, that is correct, however pronunciations:

YHVH - Yod Heh Vav Heh
Adonai - Ah-Doh-Nye
Eheieh - Eh-Heh-Yeh
AGLA - Ah-Gah-Lah

Raphael - Raff-Ay-El
Gabriel - Gab-Ree-El
Michael - Me-Kye-El
Auriel - Ohr-Ee-El

Then once you complete the LBRP put the dagger back down and do the QC again with the hands.

I would also suggest you perform an Invoking ritual as well which is the exact same except you would use the Invoking Earth Pentagram instead of the Banishing pentagram. Do the Invocation once a day to build up a charge and protection for your space and then do Banishings when you feel you need to clear something out.
