tasmāt kuru nṛpaśreṣṭha pratimādiṣu cārcanam dānāni vipramukhebhyaḥ prayaccha vidhinā nṛpa
evaṃ kṛte nṛpaśreṣṭha narasiṃhaprasādataḥ prāpnoti vaiṣṇavaṃ tejo yat kāṅkṣanti mumukṣavaḥ //

Therefore, O best of kings, perform worship in images and the like, / and distribute gifts to the best of Brahmins according to rule, O King. / When this is done, O best of kings, by the grace of Narasiṃha / he attains the splendour of Viṣṇu which seekers of liberation desire.
