Kṛṣṇadāsa Kavirāja Gosvāmī, is establishing with great stress that na caitanyāt kṛṣṇāt jagati para-tattvaṁ param iha: "There is no greater truth than Kṛṣṇa Caitanya." We are after truth, so here the author of Caitanya-caritāmṛta, he is asserting that "Here is the Supreme Truth, Śrī Caitanya Mahāprabhu." Na caitanyāt kṛṣṇāt. Kṛṣṇāt, because Kṛṣṇa has appeared as Kṛṣṇa Caitanya. We have explained this truth yesterday according to Sārvabhauma Bhaṭṭācārya's declaration, vairāgya-vidyā-nija-bhakti-yogaṁ-śikṣārtham ekaḥ puruṣaḥ purāṇaḥ (CC Madhya 6.254). Puruṣaḥ purāṇaḥ. Puruṣaḥ purāṇaḥ is Kṛṣṇa. Puruṣaḥ, He is puruṣaḥ, and purāṇaḥ, ādyam, the original person. Govindam ādi-puruṣaṁ tam ahaṁ bhajāmi **. In many Vedic literature Kṛṣṇa is described as the purāṇaḥ puruṣaḥ, the oldest. Purāṇaḥ puruṣaḥ nava-yauvanaṁ ca (Bs. 5.33). Although He is the oldest of all, still, He is always like fresh youth, nava-yauvanaṁ ca. So how it is possible? They are trying to understand God. Sometimes they paint the picture of God as very old man. Because He is the original person, so by this time He must have become very old. This is imagination. This is not actually the form of the Lord. The form of the Lord is there in the Brahma-saṁhitā and other Vedic literatures. Even Śaṅkarācārya, who is a impersonalist, he has accepted Lord Kṛṣṇa as the supreme Nārāyaṇa. In his comment on Bhagavad-gītā he says, nārāyaṇaḥ paraḥ avyaktāt: "Nārāyaṇa is beyond this material creation." And while describing Nārāyaṇa, he has affirmed, sa bhagavān svayaṁ kṛṣṇaḥ: "That Nārāyaṇa is Kṛṣṇa." And he has clearly mentioned, "Now He has appeared as the son of Devakī and Vāsudeva," to confirm just like identification is confirmed when the father's name is there.
So Kṛṣṇa is para-tattva, accepted by all ācāryas. We are not talking of the fools and rascals who are theorizing without any knowledge. We are concerned with the authorities. So authorities... Especially in India, the whole Vedic system is being followed by the people under the authorities of the ācārya. Ācāryavān puruṣo veda. One who is following the path of the ācāryas, he knows. Ācāryavān puruṣo veda. We cannot accept anyone as authority if he does not follow the paramparā, disciplic succession of ācārya. That is the Vedic system. Evaṁ paramparā-prāptam imaṁ rājarṣayo viduḥ (BG 4.2). So Kṛṣṇa is para-tattva. Na caitanyāt kṛṣṇāt jagati para-tattvaṁ param iha. He is very emphatically asserting that "There is no more greater truth than Kṛṣṇa and Kṛṣṇa Caitanya." So according to the Vedic system, if you say something very emphatically, you must prove by Vedic evidences. Otherwise you can go on talking; nobody will hear. Sometimes people ask us about Kṛṣṇa and Caitanya Mahāprabhu, that "What is the Vedic evidences?" So that Vedic evidences will be given, later chapters of Caitanya-caritāmṛta. He is not falsely asserting. Kavirāja Gosvāmī is very, very advanced devotee and scholar. He is not ordinary human being. He was empowered by Madana-mohana.
So nobody should try to write any Vedic literature. Vedic literature means the śruti, smṛti, Purāṇa. They are Vedic literature.
