Indian Hindu women dry their clothes after bathing to perform Shakh Purnima rituals at Sangam, the confluence of the Ganges, Yamuna and Saraswati rivers, in Allahabad on April 28, 2010. Sangam is one of Hinduism’s most important centres where thousands of people take holy dips as the belief that the Ganges washes away sin entices millions of Hindus into the river each year.
