Give thanks for your insight @luca1777. Yeah, I don't include Marcus Garvey in my Rastafari ideology, but instead give thanks Leonard Howell for being among the first to truly proclaim H.I.M. Haile Selassie I's divinity.
Where "prophecy" is concerned, I don't live in a supernatural world, so the only prophecies are self-fulfilling ones, and I waiting for no sky God to come down and fix everything because I prayed hard enough.
My study of history and the life of A&O caused me accept the divinity. I spent years trying to find information that would steer me away from JAH, tried Hinduism, Buddhism, even studied Haile Selassie's life from a pro-Mussolini point-of-view, and everything only served to further reaffirm my convictions.
That being said, we all make our own realities, so I don't expect any one person to have the same revelations I've had.
