The following Rite is the Left Hand path Banishing Rite that I recommend that you use.
It uses the protective energies of the Goddess and is very effective at clearing your space and yourself before and after a Rite. It uses Daemon Tongue in order to invoke the particular Goddess energies needed. It is not used to protect you from what you invoke or evoke but rather to clear our the astral entities who are attracted to your Magick that are not welcome.
The Inverse Banishing Pentagram
STEP ONE (East / Above):
Face East with your Athame in your hand at the ready. Now trace the First Inverse Pentagram visualizing it glowing before you like a flaming neon sign. Let the color be whatever your imagination gravitates to. Now point to the center of this shining Pentagram with your Athame as you intone the words (vibrate your voice like you were saying a chant):
"By the light of Isis, Guardian of the Land Of Khem,
let my spirit, mind and body be defended from evil Will!"
See Isis descend from above with her scepter in hand, her wings fully out-spread. She lands directly front of you and turns toward the East away from you warding all Evil from you and your space with her Magick, her wings, and her scepter. Feel her fierce presence fully deflecting your enemies advance as bolts of lightning flash from the clouds above.
STEP TWO (North / Aura):
Face the North and repeat the tracing of the Inverse Pentagram, point to the center and intone:
"Through the radiant essence of Hathor,
may my spirit be uplifted and made whole!"
See a massive blue and gray whirlwind of Hathor´s power come rushing to you and encircle your aura. Her power uplifts you, removes negative energies, heals you and restores your aura.
STEP THREE (West / Bindings):
Face the West and repeat the tracing of the Inverse Pentagram and point to the Center once again, the intone:
"By the Infernal Powers of Hecate and
The Primal Void of The Dragon,
let my being cleansed and empowered!"
Envision Hecate coming forth from the Abyss. She is dressed in traditional Greek garments and has pale skin with jet black hair. She cuts all negative bindings from you and frees you from heavy emotional burdens. See her four Black Jaguars (panthers) surround you and free you of all fears and anxieties.
STEP FOUR (South / Clear Vision):
Face the South and trace the Inverse Pentagram once again, pointing to the center intone:
"By the Will of Astarte, may my path be clear and my vision be sure!"
See Astarte come from the South in a fiery flash of light enshrouded by darkness. Take a moment to allow her to impart to you her blessings and powers of clarity. She will often reveal obstacles and enemies in your path.
STEP FIVE (East / Closing):
Stand facing the East with arms raised out from your sides facing North and South say:
"Before me Auset-Sekhmet!
Behind me Babalon-Hecate!
At my right Venus-Inanna!
At my left Het-Heru-Isis!
For about me shines the Pentagram
and within me burns the heart the Goddess for all time!"
