Hayagrīva: Well, man has always had a desire-basically it's a desire for God—but a desire to communicate with something outside of this world, outside of this earth, something higher.
Prabhupāda: The higher principle is there, Bhagavad-gītā, Kṛṣṇa. Why does he not communicate with Him? Then he will, that will make him perfect. What is the use of...? Just like that a tree, it has got many leaves, many branches. So if one leaf communicates with other leaf, that will not help him. But if water is poured on the root of the tree, then everyone will participate, sarva hano 'cyutejyā. So if we communicate with God, Kṛṣṇa, then automatically we understand other things. Yasmin vijñāte sarvam evaṁ vijñātaṁ bhavati (Muṇḍaka Upaniṣad 1.3). Simply by knowing Kṛṣṇa we can understand everything.
Hayagrīva: But they have sent rockets off into space and by...
Prabhupāda: That is childish. I have already explained.
Hayagrīva: Yes.
Prabhupāda: That is childish.
Hayagrīva: But...
Prabhupāda: They cannot go.
Hayagrīva: By use of, what is this radio, what do they call it? By radio waves they try to listen to messages from outer space.
Prabhupāda: That's all right, but what benefit we will get? Suppose it is not very important thing. If you hear how the persons in other plant are talking, so what benefit we will get?
Hayagrīva: Is this isolation a characteristic only of the lower and middle planetary systems? In the higher planetary system, systems, is there so much isolation?
Prabhupāda: Isolation is always there. Even in this world there is isolation, even in animals. The birds, the crows, they remain together, and the swans remain together. So there is isolation between the swan and the crows. So this isolation will continue because everyone is under different modes of material nature. There are three modes of material nature. Multiply three by three, it becomes nine. Nine by nine, then it becomes eighty-one. So, prakṛteḥ kriyamāṇāni (BG 3.27). So according to the association of different qualities the isolation is there, but when they come to Kṛṣṇa consciousness, spiritual platform, so there is no more isolation. When everyone is engaged in the service of the Lord, there is no isolation.
Hayagrīva: Bergson sees the universe itself as expanding and evolving. He writes, "For the universe is not made but is being made continually."
Prabhupāda: Yes, we also say that, that universes came from the breathing of Mahā-Viṣṇu. So just like we can imagine from breathing with the air, something may come very minute form, then it develops.
Hayagrīva: Bigger then?
Prabhupāda: Bigger, bigger, bigger, bigger.
Hayagrīva: Expanding.
Prabhupāda: One may be surprised that how this universe has come from the breathing of Viṣṇu, but actually it is so. If we accept that the universe is increasing, length and breadth, then the universe may come like particles and then begin to develop. That is the process we see in our child birth. In the womb it becomes just like a small pea, then it develops, develops as either elephant or man, the body develops. So everything material, it is created, it is very small, that a seed, very small, but it develops a big tree, banyan tree. That is the way of nature. So that's a fact that the universe is increasing. Not perpetually; to a certain extent. Then stop, again it becomes dwindled, and then it is finished.
