Kṛṣṇa says, "I am the origin of everything. Everything emanates from Me." Mattaḥ sarvaṁ prava... Sarvam means everything. There are two things: animate and..., what is opposite? Inanimate. There are two things. So Kṛṣṇa says, ahaṁ sarvasya prabhavaḥ: "I am the source of both animate and inanimate." So Kṛṣṇa. What is Kṛṣṇa? Kṛṣṇa is life, supreme life. Kṛṣṇa is not dead. We are getting Kṛṣṇa's description. He is not a dead body. These are things very, I mean to say, elaborately described in the Vedic literature. Just like in Vedānta it is said, "The origin of everything is Brahman." Janmādy asya yataḥ (SB 1.1.1), athāto brahma jijñāsā. Now this origin of everything, what is the formation, animate or inanimate? This is accepted, that Brahman means, the Absolute Truth means, the origin of everything. Now the next question would be that "What is that origin?" The modern scientists, they think the origin is chemicals. But we say, "No. It cannot be chemicals." Janmādy asya yataḥ anvayād itarataś ca artheṣu abhijñaḥ (SB 1.1.1). The origin of everything must be cognizant. He knows everything. Otherwise how He can be origin? It is very logical. Janmādy asya yataḥ anvayāt (SB 1.1.1), origin. Just like I have established this institution. I know how it was established perfectly, and how it is going on. And somebody may not know how it was established in New York with so great difficulty. But because I am the origin founder, I know. So similarly, so many things are going on in the nature's way. So the origin, He must know everything. And if He knows, then He cannot be inanimate. Where is the possibility of the origin becoming inanimate? No. Because the argument is, if one is origin of everything, or something he is origin of, he must have sense how things are going on.
So that is explained in the Śrīmad-Bhāgavatam: janmādy asya yataḥ anvayād itarataś ca artheṣu abhijñaḥ (SB 1.1.1). Abhijñaḥ. This word is used. Abhijñaḥ means cognizant. Then if He is the origin of everything, how He got all knowledge perfectly? Therefore the next word is sva-rāṭ: He is fully independent. He doesn't require to take knowledge from anyone else. Otherwise how He can be origin? Sva-rāṭ. Muhyanti yat sūrayaḥ. That origin is so perfect, and still, sūrayaḥ, many scholars, many scientists, philosophers, they are also bewildered, that "How He can be a person?" Muhyanti yat sūrayaḥ. Tene brahma hṛdā ya ādi-kavaye muhyanti yat sūrayaḥ. These things are described.
So actually, if we want to have knowledge of everything, the source of knowledge is Vedas. And the essence of Veda is called Vedānta. And the descriptive explanation of Vedānta is Śrīmad-Bhāgavatam: bhāṣyaṁ brahma-sūtrāṇām **. Brahma-sūtra. Brahma-sūtra is the Vedānta philosophy. Kṛṣṇa has also referred to Brahma-sūtra: brahma-sūtra-padaiś caiva hetumadbhir viniścitaiḥ (BG 13.5). He recommends that hetumadbhir prasthāna. There are three prasthānas, and Brahma-sūtra is also prasthāna, the way of understanding. So Kṛṣṇa has recommended that "If you want to know things with reason and argument, then try to understand Vedānta-sūtra." Those who want to know the Absolute Truth through reasoning and argument, then one should study Vedānta-sūtra. But Vedānta-sūtra... Sūtra means codes. Just like they have got code book. One word, it is meaning so many other things. Businessmen, they have got codes. When they send cable to their customer or to their principle, they use some codes. It saves so many words. So Brahma-sūtra. Sūtra means codes. So in that code also, required explanation. That explanation is Śrīmad-Bhāgavatam. Bhāṣyaṁ brahma-sūtrāṇām **. Brahma-sūtrāṇām, the codes explained in the Brahma-sūtra, that is explained in the Śrīmad-Bhāgavatam.
