Epics   
An epic is a lengthy narrative poem, ordinarily concerning a serious subject containing details of heroic deeds and events significant to a culture or nation.   

The two great epics of India are Ramayana and the Mahabaratha.  The Ramayana written by sage Valmiki is the story of Rama, king of Ayodhya who set an example as a person and a ruler.  The Mahabaratha written by sage Vyasa deals with the Pandavas, Kauravas and the Kurukshetra war.  Krishna assisted the Pandavas to establish the rule of Dharma.
