i've been wondering this for a while that why do some rastas use "yesI"? What does the I in the end change? Is it the same as "yes" except with some rasta thing in the end?
It means "yes, Neonate". The "I" is switched for "you" symbolizing that there is no difference between "I and I", only unity. There is another layer of symbolism as well, however; the number "I" appears at the end of Haile Sellasie (I) title, like Jr, Sr, etc. except for rasta, it is read as a personal pronoun, not a number. This symbolizes I and I connection to the holy "I", His Majesty.
