In the clubby world of American yoga Feurstein is often cited and recommended. Perhaps it is because he has a Ph.D. and quite a number of books published (largely recycling the same material). Maybe its because he has supplied them with effusive blurbs for their own books. Frankly, I don't see what all the fuss is about.
In my opinion, Fuerstein's writing style is ponderous yet is lacking in academic rigor. Nor do I find him to be ispiring or substantial in any practical sense. The question I ask myself is if he is not a good academic writer nor a good practical writer, why should I read him? I can't think of any reason!
One of his most irritating qualities to to present his marginal theories as if they are well accepted in authentic academic circles. Also, he cites some really insignificant writers as if they are renowned scholars, simply because they support his views. One author whom Fuerstein frequently cites has a dubious degree and is self-published. Fuerstein also cites as authoritative a book which he co-authored (a fact that is only mentioned in a foot note)that is academic junk and is published by a theosophical publisher!
On the plus side, this book is handsome and is well designed, with nice graphical images and photos throughout.
Yes, there is some interesting and valuable material contained in The Yoga Tradition. However, in my opinion getting to it is not worth the effort. There is far too much winnowing of chaff required. Still, if you want to impress your friends with the depth of your "knowledge", leave this book lying around. It just may impress them.
This is by far the most comprehensive overview of the Yoga tradition available. Clearly the fruit of a lifetime of dedicated labor!
