Kṛṣṇa can expand Himself. Just like you are sitting here. You are not in your apartment. Because you are conditioned. When you are in spiritual, liberated, you can also expand. But Kṛṣṇa, because He hasn't got material body, He can expand in million forms. He can sit here, He can sit there. Īśvaraḥ sarva-bhūtānāṁ hṛd-deśe 'rjuna tiṣṭhati (BG 18.61), He's sitting everyone's heart. Everyone, by His expansion. Although He is one He can expand. That is because He is great. Just like the sun is great. Therefore if you at noontime you send telegram to your friend who is five thousand miles away, "Where is the sun?" He'll say, "On my head." And you'll see that sun is on your head. Why? because he is great. So Kṛṣṇa being great, He can remain everywhere at one time. That is expansion. You take the example. What is sun? That is a minute creation of Kṛṣṇa. If sun can remain on everyone's head simultaneously, although one may be five thousand, then thousand miles away, Kṛṣṇa cannot remain? Why don't you use your reasoning power? Is the sun greater than Kṛṣṇa? No. Kṛṣṇa can create millions of suns. If sun has got such power, why not Kṛṣṇa? Then you do not understand Kṛṣṇa.
So Kṛṣṇa, akhilātma-bhūtaḥ (Bs. 5.37). He can expand, that you'll find in the Thirteenth Chapter. That kṣetra-jñaṁ cāpi māṁ viddhi sarva-kṣetreṣu bhārata (BG 13.3). Kṣetra, kṣetra-jñam. Just like you are a spirit soul. You are the proprietor of this body. I am proprietor of this body, you are proprietor of your body. But because I am sitting within this body, but Kṛṣṇa is the proprietor of all bodies because He is sitting everywhere. Just like this house may be owned by me or somebody else. That house may be owned by him. But the whole America is owned by the state. Similarly when there is question of greatness, that is possible, that expansion. And because I cannot expand, frog philosophy, therefore Kṛṣṇa cannot expand, that is nonsense. We are thinking always in terms of my position. How it is possible for Kṛṣṇa to expand because I cannot expand . What you are? What is your position? Why do you compare Kṛṣṇa with you? Yes, Kṛṣṇa can expand. So many examples are given. Don't think because you cannot expand, therefore Kṛṣṇa cannot expand. that is the defect of nonsensical philosophy. They formally say "God is great." But, when actually he thinks, "Oh, how much great He should be? I cannot do this. How Kṛṣṇa can do." But formally, "Oh, God is great." They have no idea how God is great. That we'll find in Bhagavad-gītā. Therefore the superexcellence of this science of God. Akhilātma-bhūtaḥ (Bs. 5.37). If you want to know how God is great then you have to take reference of this Vedic literature. No other literature.
