According to Śrīmad-Bhāgavatam, there are twelve authorities, and they are all famous because they were all great devotees of the Lord. These authorities are Brahmā, Nārada, Lord Śiva, Manu, Kapila, Prahlāda, Janaka, Bhīṣma, Śukadeva Gosvāmī, Bali, Yamarāja and the Kumāras. These personalities are still remembered because they were all great stalwart devotees of the Lord. In the Garuḍa Purāṇa it is said to be more rare to be a famous devotee of the Supreme Lord in the age of Kali than to be a demigod such as Brahmā or Lord Śiva. Concerning talks between Nārada and Puṇḍarīka, Yudhiṣṭhira said, "He is most famous and can deliver all others who, after many, many births, comes to understand that he is the servant of Vāsudeva." Similarly, in Bhagavad-gītā (7.19) Kṛṣṇa tells Arjuna:
- bahūnāṁ janmanām ante
- jñānavān māṁ prapadyate
- vāsudevaḥ sarvam iti
- sa mahātmā sudurlabhaḥ
"After many births and deaths, he who is actually in knowledge surrenders unto Me, knowing Me to be the cause of all causes and all that is. Such a great soul is very rare." In the Ādi Purāṇa it is said that liberation and transcendental life follow all the devotees of God. In the Bṛhan-nāradīya Purāṇa it is stated that even personalities like Brahmā and other demigods do not know the value of a devotee of the Supreme Personality of Godhead. The Garuḍa Purāṇa points out that out of many thousands of brāhmaṇas, one may be expert in performing sacrifices, and out of thousands of such expert brāhmaṇas, one brāhmaṇa may be expert in the knowledge of the Vedānta-sūtra, and out of many, many thousands of such Vedāntists, there may be one person who is famous as a devotee of Lord Viṣṇu. There are many devotees of Viṣṇu, and out of them, he who is unfiinching in his devotion is eligible to enter into the kingdom of God. In Śrīmad-Bhāgavatam (3.13.4) it is also stated that there are many students of the Vedas, but one who is always thinking of the Supreme Personality of Godhead within his heart is the best student of all. In the Nārāyaṇa-vyūha-stava prayers it is said that if even the great Brahmā is not a devotee of the Lord, he is most insignificant, whereas if a microbe is a devotee of the Lord, he is most famous.
