Book excerpt: After being threatened by a Bangalore mob boss, retired Indian businessman Mohan Ranga Rao makes a vow: if he somehow gets out of the situation, he will thank the gods by going on Kailash Mansarova, a holy mountain pilgrimage in Tibet. What starts out as merely a challenging high-altitude trek soon becomes a life-changing adventure. With a blend of humour, honesty and keen insight, Mohan journeys toward a deeper understanding of the world around him. A memoir of a road less travelled and a true story of self-discovery at 19,000 feet.
