It is not something yu to convert to bredren, one must take upon himself to gain knowledge and LIVE RastaFari. There is no magic ceremonies or ism skism baptism's seen. Gaining knowledge on AfriKan/Ithopian culture,the history of this world, on the life and and speeches of the Most High Living God Haile Selassie I reading the Ible and the Kebra Nestrais key.
Unity is a must, as long as we are thinking different things we will all be having differing opinons about what is the faith "Rastafari" or be it the Man "Ras-tafari" and there is of course the movement "Rastafari".
As far as I know today from you can see and declare Haile Selassie 1st the Almighty you are in, regardless of who you are, without HIM there is nothing.
