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.
The Atman alone is eternal. Hospitals will tumble down. Railroad givers will all die. This earth will be blown to pieces, suns wiped out. The Atman endures for ever.
-Swami Vivekananda
