The brahma-jyotir, yasya prabhā, is the bodily effulgence of God, Kṛṣṇa, Govinda. So on that effulgence, jagad-aṇḍa-koṭi, there are innumerable universes. It is not very difficult to understand. Just like you see in the sunshine innumerable planets are floating. So what is the difficulty to understand that there is a shining effulgence from the body of God, Kṛṣṇa, and in that shining effulgence, innumerable universes are floating? What is the difficulty? There is no difficulty. It is most scientific proposal.
So these are the potencies of God. Not that I can show some magic and immediately I become God. Just see the magic, real magic of God. Don't accept cheap God. God must show godly magic. Just like we are showing little magic, floating some airplane or sputnik or jet in the sky. We are taking so much credit—so much credit that scientists are declaring, "There is no God. I am God, because I have made this aeroplane." And what is your aeroplane in comparison to these planets? So intelligent person, they will give more credit to God than to these scientists or philosophers. Because he can see the potencies, how much potency is there.
So He has many potencies. In the Vedic literature we can understand, parāsya śaktir vividhaiva śrūyate (Śvetāśvatara Upaniṣad 6.8, CC Madhya 13.65, purport). In the Vedas, Upaniṣad: na tasya kāryaṁ karaṇaṁ ca vidyate (Śvetāśvatara Upaniṣad 6.8). God has nothing to do, personally. Na tasya kāryaṁ karaṇaṁ ca vidyate. Na tat-samas cābhyadhikaś ca dṛśyate. Nobody is found equal to Him or greater than Him. Nobody. That is God. If somebody is competitor, one God competitor, another God competitor . . .
Just like nowadays it has become a fashion to become God, and there are competition between one "God" to another. But actually, nobody can compete with God. That is God. Na tasya sama. Sama means equal; adhikasya, or greater. That means everyone subordinate. Everyone subordinate. Everyone is lower than God. He may be very powerful, but nobody can be equal or greater than God. That is the Vedic information.
Na tasya sama adikasya dṛśyate. We don't find . . . they are also, great saintly persons, they're researching that who is the greatest personality. Greatest personality. So by research work by great saintly person, especially by Lord Brahmā . . . he is the first creature within this universe. So he has found by his spiritual advancement and research work that Kṛṣṇa is the greatest. Īśvaraḥ paramaḥ kṛṣṇaḥ (Bs. 5.1).
He gives his decision: "The greatest personality is Kṛṣṇa." Just like we are sitting, so many ladies and gentlemen here, we can analyze who is the greatest here. So, say, for arguing, you can accept that "You are the greatest." But I am not the greatest. I have got my spiritual master. He has got his spiritual master. He has got a spiritual master. In this way, we go up to Brahmā. Brahmā is the original spiritual master within this universe, who gave us the Vedic knowledge. He's therefore called forefather, er, grandfather, pitāmaha. But he's also not independent.
In the Vedānta-sūtra or Bhāgavata it is said that Brahmā, he's the first creature. There was no other, any other living entity when he was created first. So if I say that he also got knowledge from others, then the argument may be, "Who is the next person to give him knowledge?" So therefore Bhāgavata says, "No. He received knowledge from Kṛṣṇa." How? "From the heart." Tene brahma hṛdā. Hṛdā. Because God, Kṛṣṇa, is sitting in everyone's heart—your heart, my heart, everyone. And He can give you instruction. His name is therefore caitya-guru. Caitya-guru means who gives conscience and knowledge from within.
