That song was composed by the first preceptor (Vālmīki) never heard of before, consisting of sounds originating from six places, containing all metres, many proofs and set in accompaniment with the music of a stringed instrument. Hearing such a song from the boys Rāma was stricken with curiosity.
तां स सुश्राव काकुत्स्थः पूर्वाचार्यविनिर्मिताम्। अपूर्वां पाठ्यजातिं च गेयेन समलंकृताम्॥ प्रमाणैर्बहुभिर्बद्धां तन्त्रीलयसमन्विताम् । बालाभ्यां राघवः श्रुत्वा कौतूहलपरोऽभवत्॥
