What are the motifs in Karma Cola: Marketing the Mystic East by Gita Mehta?

Spirituality as a commodity is a reoccurring idea in the book. Throughout the book, the author builds the thematic case that the philosophies and practices of the once spiritually purer east have, to varying degrees, become corrupted and/or tainted by the capitalistic west's perspective that spirituality is, to some degree, as much of a commodity as everything else.
