In this Wednesday, Oct. 14, 2015 photo, a Hindu priest holds an earthen lamp filled with ghee, or clarified butter, during a ritual in Bhagawatipara village, about 45 kilometers (28 miles) west of Gauhati, India. Hindus use milk and its products for religious purposes because it is believed to have purifying qualities: ghee, or clarified butter, is used in lamps for rituals; milk is used to bathe Hindu idols on special occasions; sweets made from milk or ghee are used as offerings to gods.
