After Brahman realization, after being freed from this material contamination, when one becomes actually happy, prasannātmā, na śocati na kāṅkṣati, no anxiety, at that time, samaḥ sarveṣu bhūteṣu mad-bhaktiṁ labhate parām. And He especially mentions,
- bhaktyā mām abhijānāti
- yāvān yaś cāsmi tattvataḥ
- tato māṁ tattvato jñātvā
- viśate tad-anantaram
- (BG 18.55)
If one tries to understand Kṛṣṇa, as He is, not by fiction, not by speculation, not by so-called scholarly, foolish commentation, but Kṛṣṇa should be understood as He is. Then, that is right Kṛṣṇa consciousness, and then one will be able to understand how Kṛṣṇa is working, how the whole world, material atmosphere, and material, cosmic manifestation is working. Then you will understand. Kṛṣṇa says, mayādhyakṣeṇa prakṛtiḥ sūyate sa-carācaram (BG 9.10), under my supervision. To understand Kṛṣṇa, and anyone who understands Kṛṣṇa, scientifically, then he, Kṛṣṇa says, janma karma me divyaṁ yo jānāti tattvataḥ. Not the foolish man, the intelligent man, who knows Kṛṣṇa actually, then the result is tyaktvā dehaṁ punar janma naiti mām eti (BG 4.9). Immediately he becomes liberated. So after giving up this body, he never, no more comes back to accept another, this material body. He goes back to home, back to Godhead.
