Eshu is the god who serves as a mediator between humans and the gods
or "orisha." Because he delivers the prayers, wishes and sacrifices
of men and women to the gods, humans must stay on good terms with Eshu.
Those who please him are repaid with good fortune, while those who do
not are cursed. It is for this reason that Eshu is thought of as a trickster
who represents the principle of uncertainty in life.
Images of Eshu appear on a variety of ritual objects including divination
boards, wands, staffs and clubs. Devotees carry staffs (called
opa) and amulets during ritual celebrations of the deity's power
to pay homage to Eshu.
