It is all connected somewhere wwwwwaaayyy back in time .
Ellegua is Santerias version of Ganesha .
He goes by many names,as do they all .
Eggun = Spirits/Ancestors
Elegua = Deity/Angel/Saint
Eggun comes first, then you must turn to the court of Deities/Angels/Saints, In which Elegua always comes first for them.
3) Your Deity/Angel/Saint of choice.
Many people proclaim that Spirit did not give birth to Orisha, because Obatala and Yemaya existed before man walked earth.
What they do not seem to understand is that in order for Yemaya and Obatala to exist they must have been created by Olofi/Olorun/Olodumare.
By the understanding given to us; Olofi, Olorun and Olodumare are all spirits who do not correspond to a humanoid body shape. They can enter this shape if they wish, but it is not their native shape. Natively, they are energy, which means they are spirit.
In Palo Nsambi is the same, he is not natively depicted in the shape of a person. He is energy(spirit), but he can manifest in the shape of a person if he so pleased..
