For such a short book the author wastes a remarkable amount of time on padding and on commentary on her own writing structure. I wish that there had been both more quotations from the Hindu scriptures in it, so that there was something there to taste, and also more opinion expressed - it's too even-handed on the various historical and social debates it skates over, almost to the point of being no-handed.
Sometimes Knott seems to fall into the trap of using "religion" as a category exclusive of economics, politics, etc, even as she wants to portray Hinduism as both/and. Putting "religion" in a box like that is certainly a project of moderns, and has been for several centuries, but people of many persuasions who take their faith seriously know that that is a myth. So the only people who would be surprised that Hindu practice, organisation and teaching might affect every area of life are those who have already swallowed an artificial paradigm of "religious studies" or somesuch.
Still, hopefully I know more than I did when I started (to be fair, the sense of diversity, localism, ritualism, and the variety of responses to colonialism and globalisation come across pretty convincingly) and it has slightly whetted my appetite, in the way that a piece of lettuce and a glass of water create a desire for real food.
