I have not tried the prayer because it is meant for a man who has been cheating on his partner. I do worship and honour Pomba Gira. This prayer and Pomba Gira is not to be taken lightly and the Orixas are not to be used as our personal wishing well. They work for payment and will not hesitate to take what is owed to them.
It is fairly risky working with Pomba Gira. She is a Goddess of black magick, witchcraft, love, lust, sex, Women and Queen of the Effeminate(Maria Phadila), the dead, death, the seas.She is highly revered and has a reputation of possessing those who disregard her.
SO BE WARNED. DO NOT MESS WITH POMBA GIRA.
Pomba Gira is just a name for many spirits within Umbanda. Pomba Giras are not Goddesses they are spirits like Exus these are spirits that you do not want to aproach without a Priest as you will open doors for parasitic spirits and trickster spirits which is why its very dangerous it is also so with Vodou. You need guidence of a Priest and also you need to know which Pomba Gira or which Exu you have. Do not try this because its for your own safety.
