Hillel Halkin, Across the Sabbath River: In Search of a Lost Tribe of Israel. Houghton Mifflin, 2002.  The Mizos, a people who live in a corner of India close both to Bangladesh and Burma, have practices that seem oddly Jewish. Halkin investigated them. His report includes a passage summarized on p. 40 of a review in The New Republic (Sept. 23, 2002, 39-42):

The Mizo have lived in their small far eastern corner of India for centuries. They seek to establish who their ancestors were.  Earlier in the week Halkin had received a visit from a Mizo man who spoke with a “sudden, hard candor”; “I want to know who I am. Show me I was once a Christian and I’ll be a Christian. Show me I was a Jew, and I’ll be a Jew. Show me I was an idol worshiper, and I’ll worship idols. But show me who I am.”
