ESHU is another name for an African deity, which are known as "loa", or spirit creatures. ESHU also goes by the popular name of LEGBA. He is sometimes called "Pappa Legba" and is considered as the gatekeeper of the crossroads. In order to summon this deity, his followers will often place food and libations at a place where two roads intersect. A broad square cross is his symbol as it represents the "crossroads" or the gate between the two worlds of the living and the dead.
ESHU's colors are red and black. He is known as a messenger and also as a trickster. It is said that his children are sharp and are very successful in life, due to their lack of scruples.
Ifá originated in West Africa among the Yourba groups as a form of traditional African medicine. It is also practiced among believers in Lucumi, (sometimes referred to as Santería ), Candomblé , West African & Diaspora Vodou, and similarly transplanted Orisa'Ifa lineages in the New World. In Togo, it is known as Afa, where the Vodou deities come through and speak. In many of their Egbes, it is Alaundje who is honored as the first Bokono to have been taught how to divine the destiny of humans using the holy system of Afa. The Ifa Divination system was added in 2005 by UNESCO to its list of "Masterpieces of the Oral and Intangible Heritage of Humanity".
The Yorubadivination system enabled diviners to invoke the teachings of Orunmila, the Yoruba deity of wisdom, prophecy and ethics. Esu (Eshu), who is seen as being in charge of justice and the transportation of ebos, is said to lend his authority (ase) to the oracle to clarify the issues and provide direction. Ifa divination rites are claimed to provide an avenue of communication to the spirit world.
