Indian devotees watch as 'naga sadhus' or naked holy men march in a procession towards the Sangam or confluence of the Yamuna, Ganges and mythical Saraswati rivers at the Kumbh Mela in Allahabad on February 10, 2013. Tens of millions of Hindus gathered Sunday for a holy bath in India's sacred river Ganges on the most auspicious day of the world's largest religious festival. Ash-smeared naked saints led the ritual bathing before dawn, which is said to cleanse pilgrims of their sins, with millions following them into the swirling river waters at the festival site in Allahabad in northern India.
