Prabhupāda: I have heard that before the science, the people were under the impression that this world is square. Is it not?
Devotees: Flat.
Prabhupāda: Flat. Flat, yes. But in the Vedic śāstra, millions of years ago it is mentioned: bhū-gola. Gola means round. Just see. And these rascals say that formerly people were not so intelligent. They are intelligent because they are thinking that this world is flat. And those who have spoken millions of years ago, "It is round," they will have less intelligence. Just see. Bhū, gola. Gola means round. Bhū-gola. Similarly, jagad-aṇḍa. Abda means round, just like egg. Aṇḍa means egg. Jagad-aṇḍa. This universe is egg-shaped. And we can see also, the sky is round. This is the wall of this universe.
