A Naga sadhu, or naked Hindu holy man, reflected on a mirror, ties his turban after taking a holy dip in the River Ganges during preparations for the upcoming over-a-month-long Mahakumbh fair in Allahabad, India. Millions of Hindu pilgrims are expected to take part in the largest religious congregation on the banks of Sangam, the confluence of rivers Ganges, Yamuna and mythical Saraswati, during the festival in January 2013, which falls every twelfth year.Rajesh Kumar Singh/The Associated Press
