Ādya is Bhagavān. Ādya is not Brahman or Paramātmā. Origin of everything is neither Paramātmā nor Brahman. Brahman is the bodily rays of Bhagavān. Yasya prabhā prabhavato jagad-aṇḍa-koṭi (Bs. 5.40). Yac-chaktir asti jagad-aṇḍa-cayā yad-antaḥ. Yasya prabhā. The... Just like the sunshine. Sunshine is not ādya; the sun-god is ādya. The sunshine is distributed all over the world, all over the universe. Everyone knows it. But is it ādya, is it the origin? No, no, no. It is not origin. The origin is the sun globe, or the sun-god. As soon as the sun disappears, there is no more sunshine. Therefore sunshine is not ādya. Sunshine is dependent on the sun globe. Similarly, this Brahman effulgence is dependent on the body of Kṛṣṇa. Brahmaṇo 'haṁ pratiṣṭhā. Similarly, Paramātmā is also Kṛṣṇa's expansion. Ekaṁ bahu syām. That is the Vedic instruction. He becomes many—as many living entities are there. Advaitam acyutam anādim ananta-rūpam ādyaṁ purāṇa-puruṣam... (Bs. 5.33). Ādyam again. Advaitam acyutam anādim ananta-rūpam. That ananta-rūpam, as Paramātmā or incarnation. Advaitam acyutam. But it does not mean that, because Kṛṣṇa has become many, it does not mean that, because Kṛṣṇa has become many, it does not mean Kṛṣṇa is finished. No. Kṛṣṇa is there. Pūrṇasya pūrṇam ādāya pūrṇam evāvaśiṣyate (Īśo Invocation).
This is Vedic instruction. Kṛṣṇa is pūrṇa, and if He expands Himself in millions of Kṛṣṇa... Actually, He has done so as Paramātmā. Īśvaraḥ sarva-bhūtānām (BG 18.61). There are millions. Nityo nityānāṁ cetanaś cetanānām (Kaṭha Upaniṣad 2.2.13). This bahu-vacana, living entities, they are anantyāya kalpate. They are unlimited number. There is no counting. So many. But He is the leader. Nityo nityānāṁ cetanaś cetanānām. So the, we are, living entities, we are expansion of Kṛṣṇa. Viṣṇu-tattva also expansion of Kṛṣṇa. Svāṁśa, vibhinnāṁśa. We are vibhinnāṁśa. Mamaivāṁśo jīva-bhūtaḥ (BG 15.7). But there are svāṁśa, personal expansions, and separated expansions. The separated expansions we are. We are also expansion of Kṛṣṇa. And viṣṇu-tattva also expansion of Kṛṣṇa. But viṣṇu-tattva is vibhu; we are aṇu—very, very small. Keśāgra-śata-bhāgasya śatadhā kalpitasya ca, jīva-bhāgaḥ sa vijñeyaḥ (CC Madhya 19.140). The, if you divide the top portion of your hair into one hundred parts, then take one part, again divide into one hundred parts, that is the dimension of the jīva. Therefore aṇu. Aṇu means like atom. And Kṛṣṇa is vibhu. So therefore Kṛṣṇa is ādya. Ahaṁ sarvasya prabhavaḥ (BG 10.8). Kṛṣṇa says, and Devahūti says also, the same thing.
Therefore by studying Vedic literature, we can understand Kṛṣṇa. Therefore one must seek for a Vedic teacher. Tad-vijñānārthaṁ sa gurum evābhigacchet (MU 1.2.12). Not that "At home, by speculation, I can understand what is God." That is not produce.(?) Vedas says... Just like if you want to be educated, you must accept some school. It doesn't matter whether the school is perfect or not perfect, but you cannot avoid school going. That is not possible. If you think that "Without going to school, I shall learn everything," that is not possible. Vedas says that if you want knowledge actually... Tad-vijñānārtham. Tad-vijñāna means transcendental knowledge. Because Vedic knowledge... There is material knowledge also. Just like Āyur Veda, Dhanur Veda, and Jyotir Veda. Veda, veda means knowledge. There are all different types of knowledge. But real knowledge is brahma-vidyā, to understand the Absolute Truth. That is real knowledge. Other knowledge, they are temporary. We require medicine; therefore there is Āyur Veda. We require sometimes to fight; there is Dhanur Veda. And... So that is also required. Because the body is there. But real requirement is to know the Absolute Truth, Absolute Person. Na te viduḥ svārtha-gatiṁ hi viṣṇum (SB 7.5.31). That is our self-interest. That is our self-interest. If we want to become perfect, then we must see what is the ultimate Absolute Truth. Athāto brahma jijñāsā. This is the instruction of Vedānta.
This life is meant for simply how to understand the Absolute Truth. Jīvasya tattva-jijñāsā. Jīvasya... But that is missing now. Nobody is inquiring, neither there is any institution throughout the whole world where there is tattva-jijñāsā, what is the Absolute Truth. Simply technical knowledge—how to become this, how to become that, to fill up this belly. But we cannot see even that the birds, beasts, they do not become technologists. How they are getting food? There are 8,400,000 forms of body. The human form of body are 400,000. Out of many bodies that live in jungle, they have also no technology, no education, no systematic government, nothing—but they are also eating. The birds and beasts are eating. Everyone is eating. The ants within your home, within the hole of your room, they're also eating. So who is not eating? Everyone is eating. Why you have made a civilization to work hard like an ass for your eating? What is this civilization? If everyone is, without working, they're getting their food, then what is your advancement of civilization that you have to work like an ass to get your food? That is not advancement of civilization. Therefore, because we are becoming animal, less than animal, therefore they are decreasing the personal God. This is the idea.
