That is their business. That is called durbuddhi, durbuddhi, not very intelligent. All mūḍha, asses.
Real intelligent person is he who is satisfied what Kṛṣṇa has given him: "If Kṛṣṇa wants, He will give me more. Let me become Kṛṣṇa conscious. Let me study about Kṛṣṇa. Let me chant about Kṛṣṇa. Let me hear about Kṛṣṇa. Let me see with my eyes Kṛṣṇa, the Deity Kṛṣṇa. Let me engage my hands in worshiping Kṛṣṇa, in cleansing the temple, my hands. Let my legs be engaged in going to the temple." In this way all our senses should be engaged in the service of Kṛṣṇa. That is our real business. Tasyaiva hetoḥ prayateta kovido na labhyate yad bhramatām upary adhaḥ (SB 1.5.18). Tasyaiva hetoḥ: "For that purpose only." Which purpose? Which we could not achieve after wandering the whole universe, up and down. The living entity is wandering by transmigration from one body to another up and down. Sometimes he is becoming Brahmā even. Brahmā, Indra, Candra. He can become.
