Vaitarani is the river that, according to Hindu belief, runs between the earth and the underworld, which the dead must cross to reach the realm of Yama, the ruler and judge of the dead. Because this river is said to be filled with all kinds of filth and moral offenses, Hindus believe that it can only be crossed with the aid of a cow. On this day, devout Hindus observe a fast and other prescribed rituals. In the evening they worship a black cow, who is bathed in fragrant water and has sandal paste applied to her horns. Brahmans are given gifts of food, clothes, and a cow made out of gold or silver. Discuss
