No, you won’t find any Bible verses for contrition and
renunciation here – but rather something more pointed, perhaps something even
more violent, but when all else fails: it is what must be done. 

Let it be noted
that this ritual is not one of uncrossing – as tricks and malefica can be
removed in a much simpler manner – but a solution when a great weight has been
brought about by the witch him/herself. It is for those who jumped preemptively
into breeches a size too big and are now haunted and have become a feast of
energy for parasitic beings. It must also be mentioned that this ritual is for
those beings that are unrelenting – when all other avenues have been attempted.
The reason being: the spirits herein I recommend can be very violent when
mounting/possessing he/she in need of cleansing. It is for this reason that
they are so well suited for the job, but in a weakened state (as many Sources
are) it can further compromise their system.

The Spirits of which I speak are Pomba Gira Lixeira, known
for her ability to engulf all that is malignant and unsavory without soiling
herself, and Lwa Marinette Bwa Chech, she who started the Haitian Revolution
and brought forth her people from their shackles. If you have never worked with
either, I don’t recommend you start now. If you are unfamiliar with the nuances
of Quimbanda or Voduo, this is not the
time to start. This should be done only
by (or in the company of) a seasoned practitioner. It is possible that you
may become mounted first – if you are unfamiliar with the reality of such,
there is no way you will be able to complete the ritual and may well end up
worse off than the person you are attempting to help.

As such, I will post their symbols, but will not detail the
offerings and means by which they might be manifested.

The ritual is as follows:

Ingredients

• Rum – dark or spiced, flavored with chile peppers if you see
  fit
• An egg – one from a black hen is best, though if one cannot
  be found, store bought is fine (I feel like the Barefoot Contessa)
• Water – collected from a creek, river, lake or ocean and
  poured into a glass
• Pine Tar – if you can find it
• Dusting Powder – a blend of black salt, sulfur, and cascarilla
  (other ingredients may be added, such as powdered rose or charcoal/ash depending
  on whom you work with)
• Offerings/Traditional Items Associated with the Spirits
• (Optional: Palm Fronds, Willow Whisk, or other lashing
  implements)

Instructions

This ritual is best
completed with at least two people (not including the one being “exorcised”).
That isn’t to say it isn’t possible with one, but can be a bit tricky.

Allow the Source to sit while you prepare the offerings and
mark the lines. Explain to them that this time should be used as a time to
relax, and to prepare for the coming storm. If they will have it, offer them a
tea of chamomile and ginger to sooth them. When all things are in accordance,
begin, asking the Spirits to present. Music can act as gateway.

With the Source sitting before you, kneel and place their
palms upward, taking them by the wrists. It is important to allow the Spirit to
move thusly from you to them and even more important that they remain
receptive. Reassurance is key. While their presentation can be violent, it is a
cleansing violence. Direct the Spirit into them – rolling like fire through you
and into them. When you feel the Spirit take to the new host, it may be
necessary to bind their wrists to the chair. Marinette can be particularly
violent in the hands – of course, binding presents with its own set of risks.
It’s very much up to you whether you think it right or not – and dependent on
how closely you work with the spirits in question.

Mark the Source’s forehead with pine tar (if you have it)
and gently sprinkle a pinch of Dusting Powder upon them, reciting something to
the extent of:

(Spirit Name), deliver
this child from the hands of his/her/their transgressor,
Cleanse the Spirit
with your fire and devour that which feasts upon this soul,
Purge from them the
interloper – for you sit upon their head
And now, within the
confines of this body –
Oh, (Spirit Name) –
who reigns

Take the rum into your mouth and spray it through your teeth
in a fine mist over the Source and sprinkle them again with powder, proceeding
with your reading:

(Spirit Name) –
Deliver (Name of Source)
Deliver them thusly
from this evil

Repeat the misting and dusting.

Feast upon that which
feasts upon them –
For I present it as
offering –
Let it feed the bowels
of your own existence
And let your great
fire cleanse this man/woman/person
For you are the spirit
emetic –

You may use the fronds or whisk to lash the Source – but caution need be taken, as while during the possession they will not respond to pain in the same way – it is best if reserved for the most dire of circumstances ESPECIALLY if working with Marinette, as it will infuriate her IMMENSELY

Repeat the above until you feel the destructive presence
give way to the force of Marinette or Maria, at which point, thank them for
their service. Place the egg within the glass of water and hold it above the
Source’s head, commanding (respectfully) that the Pomba Gira or Lwa depart.
Ordinarily for possession this should not be needed, but given the compromised
state of the Source at such a time, it is most surely necessary. Fulfill your
arrangement with the Spirit at a following time – as is customary. If you bound
them, release them, allowing them to relax as they will undoubtedly be
exhausted. Care for them as best you can – the rest, after, is up to them. Sleep
and hearty food is recommended – as well as healing and purifying herbs in both tea and bath.

After the ritual, the egg should be cracked into the water and the mixture returned to creek, lake, river, ocean from whence the water came.
