Brahmā’s Creation: The Kumāras, Rudra, the Prajāpatis, and the Manifestation of Vedic Sound
सनकं च सनन्दं च सनातनमथात्मभू: । सनत्कुमारं च मुनीन्निष्क्रियानूर्ध्वरेतस: ॥ ४ ॥
sanakaṁ ca sanandaṁ ca sanātanam athātmabhūḥ sanat-kumāraṁ ca munīn niṣkriyān ūrdhva-retasaḥ
सनकं च सनन्दं च सनातनमथात्मभूः । सनत्कुमारं च मुनीन्निष्क्रियानूर्ध्वरेतसः ॥
Although Brahmā created the principles of nescience as a matter of necessity for those living entities who were destined to ignorance by the will of the Lord, he was not satisfied in performing such a thankless task. He therefore created four principles of knowledge: sāṅkhya, or empirical philosophy for the analytical study of material conditions; yoga, or mysticism for liberation of the pure soul from material bondage; vairāgya, the acceptance of complete detachment from material enjoyment in life to elevate oneself to the highest spiritual understanding; and tapas, or the various kinds of voluntary austerities performed for spiritual perfection. Brahmā created the four great sages Sanaka, Sananda, Sanātana and Sanat to entrust them with these four principles of spiritual advancement, and they inaugurated their own spiritual party, or sampradāya, known as the Kumāra sampradāya, or later on as the Nimbārka sampradāya, for the advancement of bhakti. All of these great sages became great devotees, for without devotional service to the Personality of Godhead one cannot achieve success in any activity of spiritual value.
