Eshu, also known as Exu (Brazil), Eleggua (Cuba), and Esu (West Africa), is the owner of every road of life. His is the first place among the Orisha - lit. "Owners of the Head" - of the Yoruba of West Africa. Eshu must be given his offering at the beginning of every ritual or the ritual will fail or worse. His is the realm of opportunity and potentiality and the concomitant risks and perils involved in such situations. As such, his residence is at the crossroads when he is not hiding behind the front door of the home, watching all who enter and exit. A powerful ally and a hard teacher, Eshu should always be cared for and respected.
