Rituals: Great Gatherings

How massive and often extreme rituals bring thousands of people together. In Indonesia ancestors are said to ensure a good harvest for those prepared to shed human blood, so neighbouring villages have a battle on horseback called Pasola, with the intention of injuring their opponents and also being hurt themselves. Burning Man, in America, is a comparatively new ritual that draws 70,000 people together to build a community in the desert that revolves around rituals of fire. Since 2000, one crew builds a temple, which has become the centre of a mass healing ritual. Narrated by Simon Reeve
