Prabhupāda: No, not dark. They have got their light. Everywhere arrangement is there. Otherwise, how they can live?
Gurukṛpā: It's also very cold in the bottom of the ocean.
Prabhupāda: Cold for you, (laughter) not for them. (laughs) Everything, these rascal scientists consider in relation, relatively. But relative world means every living being is relatively existing with a condition. And he is thinking only his relative condition. That is their foolishness. You cannot fly in the sky; a small bird will fly. That is called relative world. For his condition, it is different from you.
Śrutakīrti: They've done filming at the bottom of the sea, and they've seen many of the fish at the bottom of the sea, in the deep portions, they make their own light. From their bodies they have light.
Prabhupāda: Yes. Just like down this planet there are dark. . . There are many other planets, Talātala. . . They are dark. The sunshine does not go there. But there are serpents who has got big, big jewels on the hood. That makes the light.
