Prabhupāda: Yes. Not that. (laughs) That Kṛṣṇa was requested by His teacher that, when He was offering that "Now I am going home. What shall I present to you, guru-dakṣiṇā, giving to the guru?" So he requested, "Kṛṣṇa, I have heard that You are so powerful. I lost my two sons. If you bring them..." So Kṛṣṇa immediately went and brought them from within the ocean. This is God. Similarly, Devakī also requested Kṛṣṇa that "Kṛṣṇa, before Your birth I lost seven children. Your maternal uncle killed them. So I want... I have heard that You have returned back the sons of Your teacher. Why not my sons?" So He brought them. That is Kṛṣṇa. Kṛṣṇa went to Kāraṇārṇavaśāyī Viṣṇu, penetrating the covering of this universe. Arjuna also went with Him. You know that?
Svarūpa Dāmodara: No. Kṛṣṇa...?
Prabhupāda: Kṛṣṇa went outside this universe, penetrating the sky. And Arjuna also accompanied Him. So it is Kṛṣṇa's power, He took His friend also. For ordinary human being it is not possible. But because Kṛṣṇa said that "All right, I'll take you." So He took him. This covering, universal covering, there are seven layers: earth, water, fire, air... Each layer is ten times bigger than the one layer. Then you go to the spiritual world.
Svarūpa Dāmodara: Ten times bigger than each layer, it increases?
Prabhupāda: That one layer, the other layer is ten times bigger than the first layer, and the third are ten times bigger than that, ten times. In this way the whole universe is covered. What your scientists know? (laughs)
Svarūpa Dāmodara: Scientists say that there are different layers in the atmosphere. There is ionosphere and all those spheres.
Prabhupāda: So anyway, some ideas are there. But in Bhāgavata it is all written.
Svarūpa Dāmodara: But they do not say that ten times.
Prabhupāda: What do they know? They do not know anything. Know something. (pause)
