Svayambhuḥ means Brahmā. Brahmā is supposed to be born without any material father and mother. Therefore he is called Svayambhuḥ. He is the only living creature within this universe who is born without the father and mother. How it is? Without the father and mother means this material father and mother.
But he has his father. His father is the Supreme Personality of Godhead, Nārāyaṇa. And he's born out of the lotus flower which is grown from the abdomen of Nārāyaṇa. Therefore he's called Svayambhuḥ. Svayambhuḥ means self-manifested. Because before him, there was no existence of material creation. Therefore he is called Svayambhuḥ.
And next is Nārada. Svayambhūr nāradaḥ. Nārada is born out of Brahmā. Svayambhūr nāradaḥ and śambhuḥ. Śambhuḥ is also born of Brahmā. Śambhuḥ means Lord Śiva. So he is also one of the ācāryas. Svayambhūr nāradaḥ śambhuḥ kumāraḥ kapilo manuḥ (SB 6.3.20). Kumāraḥ means . . .
These Kumāras, they are also sons of Brahmā, but they are called Kumāras, brahmacārīs. When they were born . . . because Brahmā wanted at that time to create living entities to fulfill the whole universe, so he wanted so many sons and grandsons. So he requested his four Kumāra sons, "My dear boys, you get yourself married and increase generation."
But the Kumāras, they said: "My dear father, we are not going to marry. We are not going to be entangled in this material way of life. We shall remain as brahmacārī and cultivate Kṛṣṇa consciousness." Oh, the father was very angry. "Oh, you are refusing my order?" So when he became angry . . . angry means that is Rudra. So from that anger Lord Śiva was born. Therefore he is called Rudra. And he was Rudra, his name was Rudra, because he was crying from the very beginning of his birth. So anyway, Rudra is also one of the authorities, Rudra, or Lord Śiva.
Svayambhūr nāradaḥ śambhuḥ kumāraḥ kapilaḥ. Kapila is the son of Devahūti, and He's also considered as the incarnation of the Supreme Personality of Godhead. And svayambhūr nāradaḥ śambhuḥ kapilaḥ kumāraḥ manuḥ. And manuḥ, manuḥ means the father of the mankind. From manuḥ, the word man is derived, or, in Sanskrit word, manuṣya. So in Latin and Sanskrit, man, manuṣya, and manuḥ, they are almost on the same level.
So svayambhūr nāradaḥ śambhuḥ kapilo kumāraḥ manuḥ, then prahlādo janako bhīṣmaḥ. So now this Prahlāda's name comes. Prahlāda's name comes. Prahlāda and Janaka, the great king, Janaka, whose daughter was married to Lord Rāmacandra, Jānakī. Therefore, Sītā's name is Jānakī, daughter of Mahārāja Janaka. So he is also a great authority.
Prahlādo janako bhīṣmaḥ, and Bhīṣma, you have heard the name of Bhīṣma, the grandfather of Arjuna. He is also one of the authorities. And, prahlādo janako bhīṣmo balir, Mahārāja Bali, a king. He was a grandson of this Prahlāda Mahārāja. He became mahājana. All these persons, they became authorities by their exemplary character for advancing in Kṛṣṇa consciousness.
