Śrīmad-Bhāgavatam
[Canto 5, Ch. 4]
TRANSLATION
[The second prayer is this.] “Who is a better worshiper of brāhmaṇas than Mahārāja Nābhi? Because he worshiped the qualified brāhmaṇas to their full satisfaction, the brāhmaṇas, by their brahminical prowess, showed Mahārāja Nābhi the Supreme Personality of Godhead, Nārāyaṇa, in person.”
PURPORT
The  brāhmaṇas  engaged as priests in the sacrificial ceremony were not ordinary  brāhmaṇas . They were so powerful that they could bring forth the Supreme Personality of Godhead by their prayers. Thus Mahārāja Nābhi was able to see the Lord face to face. Unless one is a Vaiṣṇava, he cannot call forth the Supreme Personality of Godhead. The Lord does not accept an invitation unless one is a Vaiṣṇava. Therefore it is said in  Padma Purāṇa :
ṣaṭ-karma-nipuṇo vipro mantra-tantra-viśāradaḥ avaiṣṇavo gurur na syād vaiṣṇavaḥ śva-paco guruḥ
“A scholarly  brāhmaṇa  expert in all subjects of Vedic knowledge is unfit to become a spiritual master without being a Vaiṣṇava, but a person born in a family of a lower caste can become a spiritual master if he is a Vaiṣṇava.” These  brāhmaṇas  were certainly very expert in chanting the Vedic  mantras . They were competent in the performance of the Vedic rituals, and over and above this they were Vaiṣṇavas. Therefore by their spiritual powers they could call on the Supreme Personality of Godhead and enable their disciple, Mahārāja Nābhi, to see the Lord face to face. Śrīla Viśvanātha Cakravartī Thākura comments that the word  ojasā  means “by dint of devotional service.”
