Ifa, teacher of gods and men, is the oracle of the Yoruba, an important West African people. Like I Ching, Ifa is a system of divination based on the casting of sacred objects to produce a set of signs - signs (hexagrams) in I Ching, "odus" in Ifa. But unlike the codified Chinese system, Ifa is an oral tradition transmitted and revealed only by its priests in recitations, each of which is unique.
An impressionistic, personal recitation of Ifá from Judith Gleason (Oya Lola, iba'e - the first Euro-American initiated in Lukumí-Santería back in the 1960s) and Oshogbo-based Babalawo Awotunde Aworinde. Perhaps not for the casual reader, it's full of interest to those who've been studying Odu for years, particularly as Gleason brings her interests in depth psychology and her experiences of multiple Diasporic iterations of Yoruba religion to her interpretations. Sadly out of print, like all of her books, but worth the read.
