The first thing that strikes the reader of Gurcharan Das’s new book, Kama: The Riddle of Desire, is its sheer size: Is there really, one wonders, 550 pages worth of fresh insight into what he describes as a “sense-intoxicating emotion”? As it happens, there is, and Kama is a creditable attempt to encapsulate in a single, voluminous tome the author’s informed grasp of the subject of desire. The prose flows smoothly (despite the odd repetition of a sentence on the same page, and a few typographical errors), and there is strength in Das’s exposition, enriched by an insightful reading of texts. Marcel Proust makes regular intellectual appearances, as does wisdom from the Mahabharata. We learn from the Panchatantra, even as we encounter Sextus Propertius and Anna Karenina. The book is at once a philosophical rumination as it is an explication of legendary works of literature, and on the whole stands on sound legs, adding to the author’s already impressive bibliography.
