I'm a psychic medium and I started learning about voodoo from the loas (or spirits) themselves before I met this lensmaster, Voodoomama. One day an old black man came into my consciousness. He was funny and made me laugh. He wanted me to call him Mr. Peanut. It wasn't until several years later when I started spending time with Voodoomama that I ran across something that said that Papa Legba loves peanuts. That's when I knew, without a doubt, who that "old man" was. He is a trickster at times, and he sure "tricked" me with the peanut thing.
He is also the gatekeeper into the Otherworld. If you want to communicate with any of the other voodoo loa, you have to start with him. That seems to be one of my functions in life, too, and I was born on April Fools Day so it's no wonder we are connected, even without my being a voodoo practitioner.
Voodoomama has written a great lens about Legba. You can see it here: Papa Legba. But the lens I've blessed for today is about the veves, or ritual symbols of voodoo. Each symbols represents a different loa. Learn more about them here: Ritual Symbols of the Gods and Goddesses: Voodoo Veves
