Book excerpt: Westerners often travel to India for revelation. This book chronicles three trips made there by two Westerners, the author and his wife, over nine years. Revelation did occur to them as an aspect of those trips though perhaps not in any form they might have anticipated. India is an assault upon everything from the five senses to one’s sense of history and religion, one's sense of the whole world in fact. It overturns, it overwhelms all categories and assumptions. It knocked two seasoned travelers off their bases as the pages of this book demonstrate. And enriched them too. Irruptive India.
