Prabhupāda: Strata is being created and vanquished every moment.
Svarūpa Dāmodara: So the, the background is not solid.
Prabhupāda: No. Just like the one strata is like that. After an hour, it will be different. So what is the use of your studying this strata? Therefore it is called jagat. Jagat means always changing. The material world is always changing. Your body. This body will stay, say, for fifty years, hundred years. Then you get another body. That's all. Another body. Jagat means changing. Now this color is there. Say, after one hour it will be white. You see. Then you study this black color. Again you study the white color. Again this black color. Punaḥ punaś carvita-carvaṇānām (SB 7.5.30). Chewing the chewed. That is your business. Just like seasonal changes. Now it is cold. Any moment, you'll have to get out (of) these clothes. It is very warm. So these changes are going on. The whole material cosmic manifestation is subjected to different types of changes. Therefore it is called jagat. Jagat means going, changing. Your body's changing. Similarly everything is changing. What is the eternity behind these changes? That is knowledge. That, the eternity, they do not find. Therefore they are disappointed: "It is void, zero. Eternity is zero." That's all. And when they are asked wherefrom the zero, varieties come...? Zero means there is nothing. So how the varieties come? Therefore Vedic conclusion, the varieties, there is, eternity variety. And this is only shadow of that variety. It is not eternal because it is shadow. But the real variety spiritual world, is there.
Svarūpa Dāmodara: So the material planet, material universe, is a real image.
Prabhupāda: Yes. Image. Yes. Mirage.
