na santi tīrthe yudhi cārthinārthitāḥ
 parāṅmukhā ye tv amanasvino nṛpa
yuṣmat-kule yad yaśasāmalena
 prahrāda udbhāti yathoḍupaḥ khe
na — not; santi — there are; tīrthe — in holy places (where charity is given); yudhi — in the battlefield; ca — also; arthinā — by a brāhmaṇa or a kṣatriya; arthitāḥ — who have been asked; parāṅmukhāḥ — who refused their prayers; ye — such persons; tu — indeed; amanasvinaḥ — such low-minded, low-grade kings; nṛpa — O King (Bali Mahārāja); yuṣmat-kule — in your dynasty; yat — therein; yaśasā amalena — by impeccable reputation; prahrādaḥ — Prahlāda Mahārāja; udbhāti — arises; yathā — as; uḍupaḥ — the moon; khe — in the sky.
O King Bali, never in your dynasty has the low-minded king been born who upon being requested has refused charity to brāhmaṇas in holy places or a fight to kṣatriyas on a battlefield. And your dynasty is even more glorious due to the presence of Prahlāda Mahārāja, who is like the beautiful moon in the sky.

The symptoms of a kṣatriya are given in Bhagavad-gītā. One of the qualifications is the willingness to give charity (dāna). A kṣatriya does not refuse to give charity when requested by a brāhmaṇa, nor can he refuse to fight another kṣatriya. A king who does refuse is called low-minded. In the dynasty of Bali Mahārāja there were no such low-minded kings.
