The word "Santeria" is in reference to Catholic Saints, which
are not associated with the Orisha in West Africa. Yangi stone was
not available in the new world, so Eshu started being made out of
cement filled with items; the praise name Elegbarra became
"Elleggua" in Santeria. The river Orisha Yemoja (which means
"Mother of the Fishes") became Yemaya, Orisha of all the surface of
the ocean. Oshun became Orisha of all the rivers. Both Irunmole and
Orisha were called Orisha. There are many other ways as well.
