Rastafari is a religion which developed in Jamaica in the 1930s, following the coronation of Haile Selassie I as Emperor of Ethiopia in 1930. Its adherents worship him in much the same way as Jesus in his Second Advent, or as God the Son.
International awareness of Rastafari grew in the 1970s as a result of the popularity of reggae music, and especially the international success of singer/songwriter Bob Marley. By 1997 there were, according to one estimate, around one million Rastafari worldwide.
Rastafari are monotheists, worshiping a singular God whom they call Jah. Jah is the term in the King James Bible, Psalms 68:4. Rastas view Jah in the form of the Holy Trinity – Father, Son, and the Holy Spirit. Rastas say that Jah in the form of the Holy Spirit (incarnate) lives within the human.
The wearing of dreadlocks is very closely associated with the movement, though not universal among, nor exclusive to, its adherents.
Rastafari associate dreadlocks with a spiritual journey that one takes in the process of locking their hair (growing hairlocks). It is taught that patience is the key to growing locks, a journey of the mind, soul and spirituality. Its spiritual pattern is aligned with the Rastafari movement. The way to form natural dreadlocks is to allow hair to grow in its natural pattern, without cutting, combing or brushing, but simply to wash it with pure water and herbal shampoo.
