Greetings to both African Prince and Sekhemu. For right now I am just looking this forum over checking out the discussions. I assume we are all brothers and sisters here and are open to contructive criticism and correction when needed. Correction sometimes helps me grow.
Anyway Sekhemu you loosely defined the word "awo" as divination. The word awo loosely translates as "secret, mystery". When a Babalawo does divination it is called dafa, or "to cast (da) Ifa (fa)". When one finds out their Orisa one does not have to wear white. What you described is what is called the iyawo year which is the first year AFTER initiation to a particular Orisa. However, not all people and systems require you to wear white.
African Prince and Sekhemu you can go to
http://newafrikanvodun.com/indexs.html to the New Afrikan Vodun website to learn more plus there are other links there. I hope to be talking to the both of you soon
