Another point is, as individual soul we require association, person to person. That is our nature. The Bhāgavata replies, ye 'nye 'ravindākṣa vimukta-māninas tvayy asta-bhāvad aviśuddha-buddhayaḥ (SB 10.2.32). If somebody thinks by simple impersonal realization of Brahman, if he thinks that he has become liberated, then his intelligence is polluted. Ye 'nye 'ravindākṣa vimukta-māninas tvayy asta-bhāvad aviśuddha-buddhayaḥ. Aviśuddha means not free from contamination. His intelligence is not free. Why? Āruhya kṛcchreṇa paraṁ padaṁ tataḥ patanty adho (SB 10.2.32).
The same example can be given. Suppose you are taking a jet plane to go to the sun planet or moon planet, but you are in the sunshine. You are more higher above the cloud region. Cloud is after, say, a few miles up, if you go, there is no more cloud. Finished. If you go above seven miles up, oh, there is no more clouds. There is no question of māyā. That's all right. But if you go continually, if you do not get shelter in any other planet, then the next stage will be you have to come back. You cannot remain in that impersonal sunshine. You have to take shelter. If you don't get shelter, then you come back.
Similarly, the impersonalist, for the time being they may think that they have Brahman realization, but because by nature he wants association, without getting association of the Supreme Lord he has to come back to make association with this nonsense. And this is practically we have seen. Many sannyāsī: brahma satyaṁ jagan mithyā, "Brahman is truth and the world is false." They take sannyāsa, and after some time they come to the hospital opening business. They come down again to politics, hospitals, philanthropy, welfare work. Why? If brahma satyaṁ jagan mithyā, if this whole world is false, why you are taking this hospital business? Because there is no place. He has no engagement, and he wants association. He wants to render some service, but there is no service to Kṛṣṇa. He comes to give service to the nonsense māyā.
