A former monk and long-term peace and environment activist, Satish Kumar has been quietly setting the global agenda for change for over 50 years. He was just nine when he left his family home to join the wandering Jains. Satish embarked on an 8,000-mile peace pilgrimage. Carrying no money and depending on the kindness and hospitality of strangers, he walked from India to America, via Moscow, London and Paris, to deliver a humble packet of 'peace tea' to the leaders of the world's then four nuclear powers.
