People are searching after Īśvara, "Can you show me God?" "There is no God." "God is dead." So many philosophers and theories are there, but actually there is God. Here is God, Kṛṣṇa. Īśvaraḥ paramaḥ kṛṣṇaḥ sac-cid-ānandaḥ vigrahaḥ (Bs. 5.1). Ekale īśvara kṛṣṇa. In Caitanya-caritāmṛta it is said that "Only īśvara is Kṛṣṇa, the Supreme." Ekala īśvara kṛṣṇa, āra saba bhṛtya (CC Adi 5.142). "All others, they are servants." Nobody is actually īśvara. And we find it practically. Everyone in this material world, he may become an īśvara is his group, but he is also controlled by somebody superior. That is the position of this relative īśvara. But Kṛṣṇa is absolute īśvara. Nobody is īśvara above Him. That is Kṛṣṇa. So, everyone is trying to be īśvara. This is the material world. Everyone is trying to be īśvara.
So Kṛṣṇa says that, ṛṣibhir bahudhā gītam. Because everyone is trying to be superior. Nāsau ṛṣir yasya mataṁ na bhinnā, that every philosopher must give his own opinion and it must be refuted by another. Therefore śāstra says that in this way you cannot ascertain what is the reality. Tarko 'pratiṣṭha. If you want to understand the reality by your arguments, reasoning power, that is not possible. Because I may be very nice arguer, but another person may be better arguer, he can defeat me. And that is going on.
Therefore simply by arguments, you cannot reach the Absolute Truth. That is not possible. Tarko 'pratiṣṭha. And if you simply depend on the śruti, śrutayo vibhinnaḥ. The Vedic literatures are different: Sāma, Yajur, Ṛg, Artharva. And not only that, other scriptures there are. So Śrutayor vibhinnāḥ nāsau ṛṣir yasya mataṁ na bhinnā, dharmasya tattvaṁ nihito guhāyām. To understand religious principle, it is very difficult.
Therefore our duty is, mahājano yena gataḥ sa panthāḥ (CC Madhya 17.186). "We have to accept that way which is given by the mahājana." Mahājana. So śāstra... We are sometimes in difficulty to find out the mahājana, who is mahājana. That mahājana is also described in the śāstras, who can be accepted the greatest authority, mahājana. That is stated in the Sixth Canto of Śrīmad-Bhāgavatam. Svayaṁbhur nāradaḥ śaṁbhuḥ (SB 6.3.20). They are mahājanas. Svayambhuḥ means Brahmā. Brahmā is mahājana. Svayambhu, Nārada. Nārada Muni is mahājana. And Śambhu, Lord Śiva, he is also mahājana. Svayaṁbhur nāradaḥ śaṁbhuḥ kumāraḥ (SB 6.3.20), four Kumāras. Sanat-kumārādi, they are also mahājanas. Kapila, Kapiladeva who expounded that Sāṅkhya philosophy, Kapiladeva. He is incarnation of God. Kumāraḥ kapilo manuḥ.
Svayambhuva Manu, he is also authority. Manu's name is also mentioned in the Bhagavad-gītā. Imaṁ vivasvate yogaṁ proktavān aham avyayaṁ vivasvān manave prāhuḥ (BG 4.1). So therefore Manu is also mahājana, he's authority. There is Manu-saṁhitā. Our Vedic system is conducted, the law, the law-giver is Manu. From Manu, the manuṣya, "man", these words have come, Manu. Descendant of Manu, human society, manuṣya.
