An interesting book that presents the possibility that Vedic culture was more globally dominant during ancient times. Many of the ideas sound very plausible and provide a fascinating insight into what the world may have been like spiritually and philosophically prior to the emergence of the philosophies and theologies we see in practice today. However, in his zest to make his case, the author appears to completely circumvent the normal strategies employed by scholars when presenting hypotheses. Claims are made without proper support or references, perhaps due to their "word of mouth" nature, linguistic connections are made without proper basis and without recourse to properly established theories and relationships are established which, without the proper support and given currently accepted knowledge, appear to be simply the product of the imagination. The result is a book with many interesting and plausible connections alongside emotive and unsubstantiated claims, many of which seem laughably wrong. This tends to erode the credibility of the work somewhat.
However, if the reader is willing and able to filter out the seemingly ridiculous parts there is still an interesting alternative world viewpoint to be gained from this book.
