It's important for you to know that Voodoo is heavily infested by christianity and the enemy. I would stay away from it. It's not what it use to be. Vodoo/Vodun was originally of Satan. It was a branch of Zevism long ago. Please read this article if you have not already.

Like you, I and many other blacks have felt a pull towards voodoo as its in many black gentiles soul memory but one has to discern between a pull and interest vs immersing yourself in it. Some of the gods in Voodoo are allegories and daemons of Zevism but many other of the loas and gods in voodoo are enemy thoughtforms, thoughtforms and angels, etc. That would be like mixing zevism and christianity.
Legba is an allegory for the perfected soul, the chi mercury life force energy and of Father Zeus. Dan/Damballah is the kundalini serpent energy.
It is best for you to focus on the source, which is Zevism which is the origin of it all.
