This newest volume by William Dalrymple, who is known for his finely nuanced travel writing, took shape, says the author, when he travelled to Kedarnath many years ago and ran across a sanyasi who used to be a sales manager in a refrigerator company. Such a collision of the mundane and spiritual would be notable only to a person who hardly stepped out of Delhi, but to his credit Dalrymple goes well beyond simply marvelling at it. He mentions The Canterbury Tales in his introduction, and he names his nine chapters in that tradition, presenting in each an extraordinary person who has undertaken a spiritual quest. Having put each character in a narrative frame, the author promptly withdraws to the periphery, and most of the chapter is the untrammelled voice of that person.
