Svarūpa Dāmodara: If they know that there is definitely a blissful world, spiritual world, they would not work this hard.
Prabhupāda: Yes, why? Just like Lomaśa Muni. Lomaśa Muni, his duration of life is that when one Brahmā dies, one hair from the body falls. So in this way, when all the hairs of his body will fall down, he will die. He has such a great length of... So he was standing on the side of a sea and chanting Hare Kṛṣṇa. So Nārada Muni approached him, "Why don't you make a small cottage here?" He said, "How long I shall live? (laughter) Ah, standing will do. Let me finish my bead...(?)" Just see. And here they'll live for twenty years and making skyscraper building, (makes sound:) "Doc, dong, doc, dong, doc, dong." (laughter) Does not calculate that "I shall live for twenty or thirty years."
Svarūpa Dāmodara: That is not guaranteed also.
Prabhupāda: That is also not guaranteed. Why I am taking so much trouble? They are so foolish persons. Therefore Bhaktivinoda Ṭhākura says, anitya saṁsāre moha janamiyā jīvake karaye gādhā. This so-called scientific education means people become more attracted with this temporary world and he works very hard, just like an ass. Ass, the example of ass is because the ass does not know what is his interest, but works very hard. Therefore ass example is given. Ass, he carries the washerman's cloth, tons, but not a single cloth belongs to him. He is naked. And still he is working. He does not know, "Why I am working for the washerman, carrying so much load?" That sense he hasn't got. He thinks that "Washerman gives me to eat some grasses." Although grasses are all over. That is ass. That is ass. So these scientific research workers, they are asses. He does not know that "I shall live for thirty years. So what is the use of my research work?" But intelligent man will say, "Let me utilize this thirty years to prepare for my next life." That is intelligence. But they. But they have no idea of the next life.
