Who cannot stay in the Brahman platform? The nondevotee. That is stated. Āruhya kṛcchreṇa paraṁ padaṁ tataḥ patanty adhaḥ (SB 10.2.32). Just like as you go to the moon planet but if you cannot stay there, you must have to come down again to this planet, similarly, one may rise up to the Brahman platform, paraṁ-pada, which is called paraṁ-pada, but if you cannot stay there, then again you fall down. Just like many so-called sannyāsīs, they rise to the brahma-pada, ahaṁ brahmāsmi, but because they cannot stay there, they come down again to this material world and they are busy for opening hospitals, schools and philanthropism. And why? You have left already all this nonsense, you say that this world is mithyā, brahma satyaṁ jagan mithyā. So if you have ascended to the brahma-pada, why you come down again to the mithyā-pada? That means you have no taste.
Actually you have not arrived. The same thing: You are going, the so-called advertisement, "I am going to the moon planet," but because you cannot stay there, you come down. So we have to stay there, brahma-pada. That brahma-pada staying means devotional service. Brahmeti paramātmeti bhagavān iti śabdyate (SB 1.2.11). So brahma-pada, you can rise up. But if you do not engage yourself in the service of Bhagavān, then again you come down. Āruhya kṛcchreṇa paraṁ padaṁ tataḥ patanty adho 'nādṛta-yuṣmad-aṅghrayaḥ (SB 10.2.32). Because they could not engage their service to the lotus feet of Kṛṣṇa, therefore, these so-called sannyāsīs again come down to this material platform and engage their service to the mithyā. Because they rejected this world, mithyā. Why they come down again to this mithyā platform—politics, sociology, humanity—if this is mithyā?
