So the jñānīs, who actually... No, I mean to say, jñānīs, they also immediately come. Therefore they have to try to come to this position of understanding Kṛṣṇa, many, many, births, bahūnāṁ janmanām ante (BG 7.19), not in one birth. They will have to take birth. Their so-called liberation is not possible, because if you have to take birth, then where is your liberation? There is no liberation. Liberation means no more accepting birth in this material world. That is called liberation. So Bhagavad-gītā says, bahūnāṁ janmanām ante jñānavān. Those who are cultivating knowledge, so there is no mukti. Because they have to take birth again. So in this way, bahūnāṁ janmanām ante jñānavān māṁ prapadyate (BG 7.19), when he actually comes to the knowledge point, he surrenders to Kṛṣṇa. Then vāsudevaḥ sarvam iti sa mahātmā sudurlabhaḥ (BG 7.19). This is mahātmā, when he understands that Kṛṣṇa is the... Because the perfection of knowledge means to know the ultimate source, athāto brahma jijñāsā, janmādy asya yataḥ (SB 1.1.1), from where everything is emanating. But they do not know. The scientists, philosophers, they do not know. They are simply speculating. That's all. Actually, they do not know. But when one knows, then he is perfect. And what is that knowledge? Vāsudevaḥ sarvam iti sa mahātmā sudurlabhaḥ (BG 7.19). That is mahātmā. Again, it is further explained.
Then what is the business of mahātmā? He... Suppose he understands, surrenders to Kṛṣṇa. Then what is his business? Simply knowing and surrendering will do? No. Mahātmānas tu māṁ pārtha daivīṁ prakṛtim āśritāḥ bhajanty ananya-manasaḥ (BG 9.13). Engaged in service. Not that "I have understood Kṛṣṇa. Let me sit down and sleep now." He is not mahātmā. But vāsudevaḥ sarvam iti sa ma... (BG 7.19). Mahātmānas tu māṁ pārtha daivīṁ prakṛtim āśritāḥ (BG 9.13). Daivī. Daivī means spiritual, spiritual energy. He is in the spiritual energy, not this material energy. Āhāra-nidrā-bhaya-maithuna. Spiritual energy. And what is the symptom of being in the spiritual energy? Bhajanti: always chanting Hare Kṛṣṇa, Hare Kṛṣṇa, Hare Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare. So they are mahātmā.
