A banishing ritual should be done on a Saturday when the Moon is waning.
Use a standard ritual and write on a piece of paper asking Satan to
bless the area.
Place the sigils of Flauros (Havres, Haures) and
Orobas on your altar during the ritual. These two Demons work to keep
unwanted spirits out. Ask that they be blessed and empowered, and for
Satan to send these Demons to you to protect your area.
When you
burn the paper, meditate strongly and imagine a strong electric blue
light, like a flame, run it along the ceiling, in the corners, down the
walls and the floor. If you can get your friends to help in the ritual,
your combined power will really do the job. Everyone should focus the
blue light.
Thank Satan and the Powers of Hell for blessing your area. Make sure the sigils are well protected.
Any
spirits or negative energies in the area should be banished. This
ritual may have to be repeated if the unwanted energies are particularly
strong.
