The priests were a little ashamed that King Nābhi was performing a great sacrifice just to ask the Lord’s benediction for a son. The Lord could offer him promotion to the heavenly planets or the Vaikuṇṭha planets. Śrī Caitanya Mahāprabhu has taught us how to approach the Supreme Lord and ask Him for the ultimate benediction. He said: na dhanaṁ na janaṁ na sundarīṁ kavitāṁ vā jagad-īśa kāmaye. He did not want to ask the Supreme Lord for anything material. Material opulence means riches, a nice family, a good wife and many followers, but an intelligent devotee doesn’t ask the Supreme Lord for anything material. His only prayer is: mama janmani janmanīśvare bhavatād bhaktir ahaitukī tvayi. He wants to be engaged perpetually in the loving service of the Lord. He does not want promotion to the heavenly planets or mukti, liberation from material bondage. If this were the case, Śrī Caitanya Mahāprabhu would not have said, mama janmani janmani. It doesn’t matter to a devotee whether or not he takes birth life after life, as long as he remains a devotee. Actually eternal liberty means returning home, back to Godhead. A devotee is never concerned about anything material. Although Nābhi Mahārāja wanted a son like Viṣṇu, wanting a son like God is also a form of sense gratification. A pure devotee wants only to engage in the Lord’s loving service.
