"Regarding the pastoral nature of the Indo-Aryans, Chakrabarti (1986) adds a further observation that "the inconvenient references to agriculture in the Rigveda are treated as later additions. The scholars who do this forget that effective agriculture is very old in the subcontinent, and surely no text supposedly dating from 1500 B.C. could depict a predominantly pastoral society anywhere in the subcontinent. Something must be wrong with the general understanding of this text" (Chakrabarti 1986, 76). In other words, if the Indo-Aryans were pastoralists, they must have always coexisted with agriculturists in India since agriculture predates the assumed date for their arrival by millennia. There could never have been a purely pastoral economic culture."
