avaśyaṃ tu mayā vācyaṃ leśamātreṇa bhārata
viṣṇor atulavīryasya prathitodārakarmaṇaḥ
ānupūrvyā pravakṣyāmi śṛṇuṣvaikamanā nṛpa //

Yet I must certainly speak briefly, O Bhārata, / of Viṣṇu of peerless valor, renowned for noble deeds. / I shall tell it in due order; listen, O king, with focused mind.
