Sadhus or Hindu holy men line up as they prepare to take a dip during the second "Shahi Snan" (grand bath), of the ongoing "Kumbh Mela" or Pitcher Festival in the northern Indian city of Allahabad February 10, 2013. Hundreds of thousands of pilgrims take a bracing plunge in India's sacred Ganges river to wash away lifetimes of sins, in an ever-growing religious gathering that is already the world's largest.
