Prahlāda Mahārāja, our predecessor guru... There are twelve mahājanas: Brahmā, Svayambhu, Nārada, Śambhu, Kapilo, Kumāra, Manu, Prahlāda, Janaka, Bhīṣma, Bali, Vaiyāsakir, 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. Svayambhūr 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. This is compulsory regulation for becoming human being. Without varṇāśrama institution there is no recognition of human being. Without being trained up in the varṇāśrama system there is no question of becoming human being. So actually it is not by birth as human being but by culture. Janmanā jāyate śūdraḥ saṁskārād bhaved dvijaḥ.
So Prahlāda Mahārāja is one of the twelve mahājanas. So he is speaking to his class friends. He was only five years old boy and he took the opportunity of preaching bhāgavata-dharma whenever he got some opportunity. So at that time Prahlāda Mahārāja's father, Hiraṇyakaśipu, was a great demon. He would not allow Kṛṣṇa consciousness. So still, Prahlāda Mahārāja, although he was a boy, he used to take opportunity for preaching Kṛṣṇa consciousness among his friends. So in the tiffin hours, when the boys were left free to play, so Prahlāda Mahārāja used to call them, "My dear friends, sit down. Let us talk about Kṛṣṇa consciousness." So he is preaching Kṛṣṇa consciousness. He is saying to his friends, "My dear friends," kaumāra ācaret prājño dharmān bhāgavatān iha (SB 7.6.1). The friends were very much anxious to play and Prahlāda Mahārāja says, "My dear friends. Don't play. Sit down. Sit down." Why? "A very important subject matter, Kṛṣṇa consciousness, bhāgavata-dharma."
