Pure devotees like Prahlāda Mahārāja and Dhruva Mahārāja do not aspire for any material benefit at any stage of devotional service. When the Lord was present before Dhruva Mahārāja, Dhruva did not want to take any material benefit from the Lord: svāmin kṛtārtho ’smi varaṁ na yāce. As a pure devotee, he could not ask the Lord for any material benefit. In this regard, Śrī Caitanya Mahāprabhu instructed us:

na dhanaṁ na janaṁ na sundarīṁ kavitāṁ vā jagad-īśa kāmaye mama janmani janmanīśvare bhavatād bhaktir ahaitukī tvayi

“O my Lord, Jagadīśa, I do not pray for benedictions by which to achieve material wealth, popularity or beauty. My only desire is to serve You. Kindly engage me in the service of the servant of Your servant.”

Thus end the Bhaktivedanta purports of the Seventh Canto, Ninth Chapter, of the Śrīmad-Bhāgavatam, entitled “Prahlāda Pacifies Lord Nṛsiṁhadeva with Prayers.”
