When one is brahma-bhūtaḥ, self-realized, he's prasannātmā, joyful, ānandamaya. Brahma-bhūtaḥ prasannātmā na śocati na kāṅkṣati (BG 18.54). He has no desire to fulfill, neither he has lamentation. Here, in the material world, we hanker after things which we do not possess. "I want this. I want that." And we cry when the thing is lost. Na śocati. But a brahma-bhūtaḥ, when one is self-realized, when one knows that he's not this body, he's spirit soul, he's part and parcel of Brahman, at that time, he becomes joyful. Brahma-bhūtaḥ prasannātmā na śocati na kāṅkṣati, samaḥ sarveṣu bhūteṣu. And he sees everyone on the equal footing. Because Brahman-realized. He knows everyone is not this body. He's spirit soul, part and parcel of Supreme Brahman. This position, when one comes to this platform, brahma-bhūtaḥ stage, mad-bhaktiṁ labhate parām. That is the stage to be promoted to the Brahman activity.
The nirviśeṣa, impersonalists, they want to stop activity, but actually Bhagavān, Kṛṣṇa, says that real activity begins when one is self-realized, one is situated in Brahman realization. Brahman realization does not mean to stop. Brahman realization means to act for Kṛṣṇa, not for sense gratification. That is Brahman realization. Mad-bhaktiṁ labhate parām (BG 18.54). And in that bhakti stage, bhaktyā māṁ abhijānāti yāvān yaś cāsmi tattvataḥ (BG 18.55). Actually, simply by executing devotional service, being freed from all material contamination, when one is engaged in devotional service, bhakti, that process, bhakti process can help one to understand what is God. Bhaktyā mām abhijānāti. It is not said that by karma, "karmaṇā mām abhijānāti." No. "Jñānena mām abhijānāti." Abhijānāti, tattvataḥ, if one wants to know God in truth, then he must take to devotional service. And this devotional service, actual devotional service begins when one is Brahman realized.
So one may argue, "Does it mean that all the bhaktas... We see they are not even educated... How he has realized Brahman?"
