Karandhara: At the end of Brahmā's daytime there is pralaya with the water?
Prabhupāda: That is water full. So we know everything.
Svarūpa Dāmodara: Scientifically it sounds also very reasonable.
Prabhupāda: Hah?
Svarūpa Dāmodara: Scientifically . . . for example, when there is a very strong heat, necessarily the water evaporates.
Karandhara: As soon as it rains, then again things start flowing.
Prabhupāda: Huh?
Karandhara: That's scientific.
Prabhupāda: Everything is scientific, they are not bogus. They are real scientific. Here, only speculating. (pause)
(break) Your speculation for solving the problem is useless. Nature will go on with its work. You cannot stop.
Svarūpa Dāmodara: We see every day the waves always moving. The force of nature.
Prabhupāda: Daivī hy eṣā guṇa-mayī mama māyā duratyayā (BG 7.14). You cannot stop nature's force. That is not possible. You can simply surrender to God, and He can give you in any circumstance. That is the only way. Pralaya-payodhi-jāle dhṛtavān asi vedaṁ (Daśāvatāra Stotra 1).
Svarūpa Dāmodara: So all these people spend their time, whole time, in worrying about future.
Prabhupāda: Yes. They will worry, and they will be annihilated at the same time. Because they have no shelter. That is the future.
Karandhara: They spend all their time worrying about death, but they don't do anything. They can't stop it.
Prabhupāda: Yes. Simply being worried about death, does it mean that death will be stopped?
Karandhara: No.
