 In the latter book, Frawley, Georg Feuerstein, and Subhash Kak reject the Aryan Invasion theory and support Out of India.Bryant commented that Frawley's historical work is more successful as a popular work, where its impact "is by no means insignificant", rather than as an academic study,
and that Frawley "is committed to channelling a symbolic spiritual paradigm through a critical empirico rational one".Pseudo-archaeologist Graham Hancock (2002) quotes Frawley's historical work extensively for the proposal of highly evolved ancient civilisations prior to the end of the last glacial period.
