There are two great epics in Hinduism, which are very ancient. They are the Ramayana and the Mahabharata. They embody the manners and customs, the state of society, civilisation etc., of the ancient Indians.
We must be bright and cheerful. Long faces do not make religion. Religion should be the most joyful thing in the world, because it is the best.
-Swami Vivekananda
