As a shaman, Sipa Melo is the beating heart of tribal faith and culture in a remote corner of north-east India, tucked in the shadow of the Himalayan Mountains. He's a healer, a story-teller and a protector of the natural world. Antonia Bolingbroke-Kent joins Sipa for a week of ritual, performing ceremonies to mark deaths and births and maintaining taboos that help preserve this mountainous region's indigenous culture and its rich wildlife. She hears about his determined efforts to encourage a new generation of trainee shamans and his worries about the changing values of the region as roads and hydro-electric dams end its isolation from the booming cities to the south.
