The order of Sadhu in India dates back more then five thousand years. Although there are four to five million of them, they don't actually constitute more than about half a percent of the total Indian population. In their pursuit of  the 'inner light' -- the liberation from all earthly bonds -- they live a life free of possessions, comforts, sensual pleasures and earthly responsibility. This suggests a systematic 'reprogramming' of body and mind by various methods, such as celibacy, renunciation, religious discipline, mediation and austerities. In all the years I have been traveling to India I have been struck by the power of their otherworldliness and great physical beauty. In this increasingly consumerist, global culture we live in I always carry a fear within me that the next time I come to India my camera will have less of these amazing souls to focus on. But the world needs our Sadhus and I remain optimistic.
