"Moreover, in [RV 2.20.7 , 1.101.1] , Geldner's translations of the krsnayonih... as meaning 'having blacks or embryos of the blacks in their wombs' is quite recherché; a more natural interpretation would be 'having dark wombs', and this interpretation permits a reading 'having dark interiors' - which could refer either to dark interiors of the dasas forts or to the dark world in which the forts of the dasas /dasyus are located , in contrast to the 'light' world of the aryas. In fact the close similarity between the expressions... 'he created land for Manu' in [RV 2.20.7] and... 'making broad light for the arya' in [RV 7.5.3 - 6] provides strong support for the view that words for light and dark are indeed used to refer to the earth, land, or world of aryas vs dasas."
