Personally I think that’s where most people get it wrong. I’d consider Petro a family name or a title or maybe even a description for the type of Loa you find within the Petros.
I don’t believe it’s simply an aspect based on my works and if they are, they’ve developed into full blown personalities over time.
If you call Legba, Kalfu, Bossu, and Taureau-trois-graines you will get four very distinct Loa whose personalities don’t match or overlap and neither or rarely do their back stories.
Historical accounts do not say Kalfu sometimes called Legba. At least as far as I’ve seen, they just don’t and neither do any accounts I’ve read from practitioners.
I can’t ever discern a legitimate reason to believe this when someone suggests it, especially when you try to pull clairsentience or claircognianze information to confirm what these people are saying.
Of course I’m speaking as someone whose tried to research them since before recorded history and starting beyond ancient Nigeria and Egypt. As I’ve said it’s very hard to nail down with legitimate documents.
It’s not nearly so hard to nail down what the Loa themselves say about this or the claircognianze and clairsentience information- that’s just hard to put into words when people with zero discernment believe everything they read and assume they can trust people and works based on something other than this information because they can’t confirm it themselves.
If you look into it however, there are many names with Petro or Radha etc and they often follow a title like the Damballahs, Ezulies etc.
If you look at the name combination you can derive what skills or powers that Loa has without their backstory and you can confirm these skills with the story that tells how they used their skills and under what circumstances.
Under the context in which they used these powers and skills you can determine what types of rituals and works they will be well suited for.
For example a Loa that was a martyr defending his raped and murdered wife, makes for really good justified revenge, but not for really good baneful work against unjust targets or for killing or attacking the spouse of your secret love or breaking up couples.
You may find in time you stick with what you read or assume and you may someday feel silly for the assumptions you made. I personally feel stupid for believing other magicians and books in regards to the Loa as I would have benefited much more if I’d just allowed and accepted instead of thinking it had to be this or that way because most voodoo people said this or that.
I’ve found in truth, that most legit voodoo practitioners actually agree with me, and it’s usually only the ones trying to make a living scamming people with their knowledge and services that seem to be absolutely livid at my suggestions.
However occasionally a good hearted person does the same thing an over zealous anyone does and gets upset at something they know is true but don’t think the public should know or that they don’t want to believe they were misled on.
Either way, the best thing you can do is work on your discernment and figure out a plan for confirmation as you won’t find confirmation outside of yourself for most things.
People just aren’t talking about the Loa in common terms you see on the forum or in average evocation and invocation settings.
They aren’t using these methods, so they aren’t speaking this way and they aren’t getting the same types of results because most are not operating like this.
For example veves weren’t truly meant to work like a sigil, it just seems to be happenstance that they do. Real voodoo practitioners don’t use the veves quite like me and you are. They inscribe them on things yes, but they don’t use them as the calling card for summoning.
The average practitioner working with the Loa does not seem to be approaching as a student or respectful equal looking to learn, they seem to approach as a worshipper or devotee who will often be a student as well, but who will often depend very heavily on their payments of offerings rendering favor in the relationship and with results.
These things change the context very quickly imop and make it difficult to compare what you are doing to what anyone else is doing.
So I don’t. I don’t practice voodoo, I work with the Loa in a completely different context as that so I don’t expect to get the same exact result or appearances or any of that because I try to allow things to be what they are instead of fitting them into things the way I think they should.
I don’t get it all right, but it works pretty well for me, so I’m sure with some work on discernment and practice you’ll figure this can’t discern who they are stuff out.
