दृष्ट्या पापीयसीं सृष्टिं नात्मानं बह्वमन्यत |
भगवद्ध्यानपूतेन मनसान्यां ततोऽसृजत् ||३
सनकं च सनन्दं च सनातनमथात्मभूः |
सनत्कुमारं च मूनी न्नष्क्रियानूध्वरेतस ||४
When Lord Brahmā decided to commence the sequence of creation, he created five types of ignorance- tama, moha, mahā-moha, tāmisra, and andhatāmisra. Seeing what a troublesome creation it was, he could not really appreciate his own doing. Thus, after purifying his mind by meditating upon the lotus feet of the Supreme Lord, Brahmā thought of doing it (the creation) all over again for the second time. Then, Brahmā created the four Kumāras- Sanaka, Sanandan, Sanātana and Sanat-kumāra, who are eternally liberated and are lifelong celibates. The above sequence of events are mentioned in the Srimad Bhāgvat Mahāpuran- Canto 3- Chapter 12- Verse 3 and 4.
The four Kumāras are also known as ‘mānas putra’ or the sons born out of Brahmā’s contemplation. Famous throughout the Puranic literature, they are renowned yogis, who requested their father- Brahmā for the boon of remaining five years old perpetually. They can travel freely to any of the lokas (planes of existence) and are one among the 12 Mahajans- knowers of the divine principle (Bhagavat-dharm).
It is found in Padma Purana that Nārad Muni’s quest for real knowledge led him to the four Kumāras. Upon this, the four Kumāras tell Nārad that as long as people do not hear Lord Krishna’s pastimes, Bhakti does not get established in their hearts. Without Bhakti no one can obtain real knowledge, nor can they understand the real meaning of true detachment. The only necessary thing to invite Bhakti, Gyān and Vairagya in one’s heart is listening to Srimad Bhāgavatam. On hearing this, Nārad Muni requested the four Kumāras to narrate the Srimad Bhāgavatam. The four Kumāras obliged Nārad and thus became the narrator of the Srimad Bhāgvat Mahāpuran.
