Śrīmad-Bhāgavatam 7.6.1 — December 2, 1975, Vṛndāvana 751202SB-VRNDAVAN [28:28 Minutes] SB-07.06.01_751202SB-VRNDAVAN Prabhupāda: ...this table here. kaumāra ācaret prājño dharmān bhāgavatān iha durlabhaṁ mānuṣaṁ janma tad apy adhruvam arthadam [SB 7.6.1] Prahlāda Mahārāja, our predecessor guru... There are twelve mahājanas: Brahmā, Svayambhū, Nārada, Śambhu, Kapila, Kumāra, Manu, Prahlāda, Janaka, Bhīṣma, Bali, Vaiyāsaki, vayam. Mahājano yena gataḥ sa panthāḥ [Cc. Madhya 17.186].
It is said in the Vedas that we have to follow the footprints of mahājana. Mahājana means great authorized devotees. And they have been described, twelve. Svayambhū means Lord Brahmā; Nārada, Nārada Muni the great saint; Śambhu, Lord Śiva...
Svayambhūr nāradaḥ śambhuḥ kaumāra [SB 6.3.20]—the four Kumāras, sanat-kumāra ādi. Then Kapila, Kapiladeva, Devahūti's son. There are two Kapilas. So one is imitation; one is real.
The real Kapila, He is known therefore Devahūti-putra, "the son of Devahūti." Devahūti was the daughter of Manu, Vaivasvata Manu. So in this way, kapilaḥ kumāro manuḥ. Then Prahlāda Mahārāja. Prahlāda Mahārāja was the son of Hiraṇyakaśipu, the famous demon.
So it is not that a demon's son will be demon. That is not... Kṛṣṇa consciousness can be achieved by anyone. Kṛṣṇa says in the Bhagavad-gītā, māṁ hi pārtha vyapāśritya ye 'pi syuḥ pāpa-yonayaḥ [Bg. 9.32].
Pāpa-yoni means to take birth in low class family or demonic family. So pāpa-yonayaḥ. Kṛṣṇa says openly, ye 'pi syuḥ pāpa-yonayaḥ. Anyone, it doesn't matter, even if he is born in a pāpa-yoni...
Pāpa-yoni means generally less than the śūdras. According to our Vedic system, four classes, varṇāśrama, social and spiritual division. The social division is brāhmaṇa first, then kṣatriya, then vaiśya, then śūdra. This is social division, and there is a spiritual division: brahmacārī, gṛhastha, vānaprastha, sannyāsa.
