I am reading 'Mustang a lost Tibetan kingdom' by Michel Peissel. I have read 'Three cups of Tea', 'Snow Leopard', '7 years in Tibet', 'Into the thin air' in past few years. I will also read 'Buddha's warriors' as I have found it resourceful to know more about cultural revolution in Tibet.
The book I am reading now 'Mustang a lost Tibetan Kingdom' explains the place as hidden paradise, where wheels were not used and earth was thought to be flat. 'Sky burial', polyandry, Tibetan bandits, Shakya Buddhist royal family, Tibetan medicine practice, meditation caves witnessed by writer in as late as 1960es make it sound like a hidden Shangri La.
