On seeing that pair intellectuals who are proficient in Veda-s that self-reliant sage Valmiki made those two to memorize the epic, as the epic Ramayana is composed only to reinforce the import of Veda-s, as an ancillary. [1-4-6]
That sage with observed sacred vows has rendered the entire epic in the name of 'Ramayana', 'Sublime Legend of Sita' and 'elimination of Ravana'. [1-4-7]
पाठ्ये गेये च मधुरं प्रमाणैस्त्रिभिरन्वितम् | जातिभिः सप्तभिर्बद्धं तन्त्रीलयसमन्वितम् ||१-४-८
To read or to sing it is melodious, adaptable to music with three scales and sevenfold tune, and orchestral to the tunes of string-instrument and rhythm included... [1-4-8]
Aesthetics like romance, pathos, comic, fury, fright, valour etc., embodying the epic is sung [by Kusha, Lava.] [1-4-9] (Rama's togetherness with Sita from Bala Kanda till her abduction is the first category of romance. After her departure and until regain, it is second sort of romantic narration. Episodes of Surpanakha, Trijata are humorous. Those of Dasharatha, Jatayu etc., are of grievous nature. Killing, torturing etc., situations arouse furiousness. Lakshmana, Indrjit and others are showing bravery. Seeing ugly demons either in forests or those that surround Sita is causing fright. The very sight of ugly bodied demons like Viradha, Kabandha is creating disgust. Hanuma's leaping ocean, burning Lanka, and the entire Rama-Ravana war are amazing)
