My knowledge takes me in a different direction. I have read Bernard Lewis' Race and Slavery in the Middle East, and he's recognized as a foremost scholar on the subject. I've read Cheik Anta Diop, Maulana Karenga, Echoes of the Old Darkland: Themes From The African Eden by Dr. Charles Finch III, Jacob Carruthers, Asa Hilliard and others, and I just don't find Arabs enslaving Africans...to the degree that you're promulgating here...
And no...ayruveda is not recognized in the cosmic science of astrology, whose basis are the four elements of the Universe...earth, water, air and fire...
(I know you from Afrocentriconline ifasehun...)
