I am posting this in case anyone things I am inventing the meaning. rsrsrs A soul sister is merely a Black female. A soul mate is an entirely different term. Soul means Black, Afro-American. Take a look at some of its uses:
soul music = Afro-American music (Did "Soul Train" get to Brazil? Lots of soul music!)
soul food = Afro-American food (Love peach cobbler! In Brazil, feijoada, vatapá, acarajé, etc. probably started out as soul food.)
Soul City = Afro-American part of Saigon.
"We've got more soul..." = Lyrics from an Afro-American song from the 1960s.
Soul Kitchen = Name of Afro-American restaurant
