Sage Valmiki goes to river Tamasa for a bath and sees a couple of birds, of which a hunter kills one. Valmiki unintentionally utters a poem, which is rich in grammar and new in metre, of which he is very much confused as to why such a poem has come from his tongue. Brahma, the presiding deity of letters appears and ordains Valmiki to author Ramayana, excellent epic of Rama, for which purpose alone he gave such divine meter and grammar to him.
