(1) Could you please tell me some differences between the Lwa Ogou Feray and Ogou Badagris?

Papa Ogou is one of the great Lwa of Haitian and New Orleans Voodoo.  Primarily a warrior Spirit, He carries all the "Mars" associations of the male gender - the color red, blood, fire, lightning, the sword, the metal worker, and also, the magical connotations associated in many cultures with the blacksmith. As Ogou Badagris, He is associated with a particular coastal region of Nigeria, and is often depicted as an older general and decorated soldier. As Ogou Feray, He is associated with iron, metals, and the sword, and often depicted as a younger, virile soldier. Stability, order, authority, justice, and persistence are all associated with the Ogous as a whole. 

(2) Can you please tell me about the way Yemaya sends messages? Last night I heard seashells shaking in my bedroom. It was the most beautiful sound, and so comforting.  

She is the Orisha of the Ocean, amongst other things and representations of Her are often adorned with sea shells. She is very mothering and must have felt you needed the peace & comfort. Spirit communication is a very personal thing and we feel that it's best to trust your instincts on the matter. If you feel Yemaya is speaking to you, listen to her messages and do your best to interpret them and apply them to your life.

(3) Do Voodoo Practitioners really think that zombies are real?

The best exploration of the phenomenon of zombification is Harvard Scientist/Ethnobotanist, Wade Davis' fantastic book "Serpent & the Rainbow” (By the way, don't think, "I'll save time & just rent the movie." It's not the same!).  In it, he shares the experiences he encountered while doing research in Haiti - research which proved that Zombies & the formula which creates them are both very real.  Be that as it may, the creation of Zombies is not a part of the traditional Voodoo practice – it is in fact frowned upon by both honorable Mambo & Houngan alike. It is more the province of the bocor/bokor.

(4) What is a bocor/bokor/boko?

A bocor/bokor/boko is a sorcerer who performs Spiritual Work for clients in return for gifts or money.  What separates them from other practitioners is that, in general, they "work with both hands."  In other words, they will perform many rituals involving black magick & will-control that most other initiated Vodou practitioners will not.
