If one jñānī is impersonalist, he's not jñānī. He is still unaware of the Absolute Truth. He does not know. Therefore it will take many, many births to come to the understanding of the Personality of Godhead. Therefore he's not jñānī; he's claiming to be jñānī. Such jñānī will take many hundreds of births to come to the position of real jñānī. Find out this bahūnāṁ janmanām ante (BG 7.19). (devotee reads in French) So-called jñānī, after many, many births, when he understands Kṛṣṇa and surrenders to Him, then he's jñānī. Sa mahātmā sudurlabhaḥ. That kind of jñānī is very, very rare. The impersonalist means ajñānī. Yes. Because he does not know Kṛṣṇa, the person.
There is another verse in the Śrīmad-Bhāgavatam: āruhya kṛcchreṇa paraṁ padaṁ tataḥ patanty adhaḥ (SB 10.2.32). Āruhya kṛcchreṇa, by the jñāna process, is undergoing austerities and penances, one comes to the platform of paraṁ padam, monism, or platform of oneness. But because he has no shelter, he patanty adhaḥ, again comes to the material. Just like so many sannyāsīs in India, they are very learned, they have come to the platform of Brahman realization, but after some time they come to the material field for political work, for social work. They give up this world, brahma satyaṁ jagan mithyā. If jagat is mithyā, is false, why does he come for social work? Just like these people going to the moon planet, but because they do not get any shelter, they take some sand and come back again. So what is the use of going there and spending so much money and come back with little sand, and satisfied, "Now we have studied"? Because they have no shelter. So the jñānīs, they have no shelter. Yes. They may go very high in the sky, but because they have no shelter they come back again. Punar muṣaka bhava: again became a mouse. So that is not jñānī; that is ajñānī. Jñānī is described here, mad-bhaktiṁ labhate parām (BG 18.54). Brahma-bhūta (SB 4.30.20) is jñānī, ahaṁ brahmāsmi. Brahma-bhūtaḥ prasannātmā, "I have nothing to do with material world." Brahma-bhūtaḥ prasannātmā na śocati na kāṅkṣati (BG 18.54), there is no lamentation, there is no hankering. When he has attained that stage, brahma-bhūta stage, reality, then he is entrance in the bhakti. Otherwise a neophyte.
Bhūgarbha: He says that any person on the path of knowledge who rejects the Personality of Godhead, his knowledge is finished.
Prabhupāda: That is sublime knowledge. When you talk with the Supreme Personality of Godhead, dance with Him, that is sublime perfection. Otherwise, you will have to dance with the dog.
Bhūgarbha: He's asking that since he first read the Gītā when he was very young, since that time he's been trying to compact paths of jñāna and bhakti and follow the teachings of all the great religions. And he's wondering if he should continue on that same path.
Prabhupāda: No, jñāna means that to understand the Absolute Truth. If you do not understand the Absolute Truth, what is the meaning of this jñāna? That means knowledge is imperfect. So, but if you want to know the Absolute Truth, ultimately, then bhakti is required. That is stated in the Bhagavad-gītā: bhaktyā mām abhijānāti yāvān yaś cāsmi tattvataḥ (BG 18.55). If you want to know the Absolute Truth, the Supreme Being, then you have to go through bhakti. Jñāna, so-called jñāna, bhakti includes. Just like bhakti includes everything, but jñāna does not include bhakti. It is imperfect. In jñāna there is little touch of bhakti, but in bhakti there is full jñāna. Because unless you . . . absolute Truth is realized in three stages, brahmeti, paramātmeti, bhagavān iti śabdyate (SB 1.2.11). So those who are on the stage of Brahman and Paramātmā, they're not in the Absolute Truth. Part of it. But when one understands Bhagavān, then he understands Paramātmā and Brahman. That is full knowledge. There are three things—sat, cit, ānanda. So Brahman realization is sat. Paramātmā realization is cit. But ānanda is not there. But if he does not get ānanda, then falls down.
