So Caitanya Mahāprabhu, when He was traveling in the southern part of India, south India, Ādikeśava Mandira, there was a temple. Still that temple is there. He found out this Brahma-saṁhitā in handwritten. Formerly, there was no printing press. So any important Vedic literature was being copied. Suppose you have got some copy. I want it, so I borrow from you the book, and I copy in my handwriting or I engage somebody who has got good handwriting. In this way, in Vṛndāvana, still there are so many handmade, handwritten literatures. They have opened one association, one society. They are collecting all this handwritten literature. So this handwritten literature, Brahma-saṁhitā, was collected by Caitanya Mahāprabhu from a temple in South India, and He delivered to His immediate disciples, that "This is Brahma-saṁhitā, written by Brahmā. It is the summary of the Bhāgavata, Śrīmad-Bhāgavata."
So Caitanya Mahāprabhu gives reference of Śrīmad-Bhāgavatam with Brahma-saṁhitā. That means Śrīmad-Bhāgavatam also is eternal. They are not man-made, manufactured books. The Vedic literature means, as it is stated in this verse, tene brahma hṛdā. Brahma means Vedic literature, śabda-brahma. So He distributed the... Vāsudeva, original person, Absolute Truth, He, I mean to say, transferred this Vedic knowledge. Tene brahma hṛdā. Brahmā was alone. He could not see Kṛṣṇa eye to eye, but īśvaraḥ sarva-bhūtānāṁ hṛd-deśe arjuna tiṣṭhati [Bg. 18.61]. Kṛṣṇa is everyone's heart, so He taught him from within. Kṛṣṇa's name is Caitya-guru, "guru, spiritual master from within." So Kṛṣṇa is trying to help us from within, and He manifests again externally also as spiritual master, directly teaching. So from within, from without, He is trying to help us. Kṛṣṇa is so kind. From within and without. Tene brahma hṛdā ādi-kavaye [SB 1.1.1].
So this Brahma-saṁhitā was written by Lord Brahmā, and in Brahma-saṁhitā the name of Kṛṣṇa is there. Īśvaraḥ paramaḥ kṛṣṇaḥ [Bs. 5.1], beginning. That is the fifth chapter. There were hundred chapters. Only fifth chapter is available. So in the beginning of that fifth chapter, Brahmā says, īśvaraḥ paramaḥ kṛṣṇaḥ sac-cid-ānanda-vigrahaḥ [Bs. 5.1]. So how these rascals can conclude that Kṛṣṇa was liv..., some years, some hundred or five hundred years ago there was a beel boy, he was very powerful. So in this way, these rascal so-called scholars they are misleaded public. Therefore we call them simply rascals. They do not know what is the truth, and still, they write books, they write commentaries unauthorizedly and mislead public. This is going on. Kṛṣṇa is not manufactured. In the Brahma-saṁhitā there is complete description of Kṛṣṇa:
īśvaraḥ paramaḥ kṛṣṇaḥ
sac-cid-ānanda-vigrahaḥ
anādir ādir govindaḥ
sarva-kāraṇa-kāraṇam
[Bs. 5.1]
The cause of all causes. Janmādy asya yataḥ [SB 1.1.1]. Vedānta-sūtra says, "The Absolute Truth is that which is the origin, original cause." Original cause. The scientists, they are trying to find out the original cause of creation, but they are creating their own imagination. "There was a chunk, and it burst out, and then planets came out." Like that. (laughter) And wherefrom this chunk came, you nonsense? So this is going on.
