tato hariḥ kalkisaṃjñaśca vīndra utpatsyate yugayormadhyasaṃdhau /
dasyuprāyānbhūmipānvai nihantuṃ nāmnā harirviṣṇuguptasya gehe //

Then Hari, named Kalkin, O King of Birds, will be born at the junction between the two yugas, / to slay the earthly rulers who have become like thieves, Hari [born] in the house of Viṣṇugupta.
