Indian Hindu devotees pose for a photograph as they pour water over a sadhu, or holy man, as they take a holy bath and perform rituals at the Gangasagar Island, some 150 kms south of Kolkata, on January 14, 2016.  More than 500,000 Hindu pilgrims and sadhus - holy men - are expected to gather at the confluence of the River Ganges and the Bay of Bengal during the Gangasagar Mela to take a 'holy dip' in the ocean on the occasion of Makar Sankranti, a holy day of the Hindu calendar considered to be of great religious significance in Hindu mythology.
