So we have to understand what is Kṛṣṇa. And as soon as you understand Kṛṣṇa, janma karma me divyaṁ yo jānāti tattvataḥ, in truth, if you understand Kṛṣṇa, then you become liberated. Tyaktvā dehaṁ punar janma naiti mām eti kaunteya (BG 4.9). So we have to understand Kṛṣṇa like that. Sva-tanvā: He left this body not as we leave our body. No. We are leaving and accepting our body by the force of nature, material nature. Prakṛteḥ kriyamāṇāni guṇaiḥ karmāṇi sarvaśaḥ (BG 3.27). Our business is going on being forced, enforced by the laws of nature. Kṛṣṇa is not under the laws of nature; neither He has got distinction between His self and body. This is to be understood. Sva-tanvā. If somebody thinks that "Kṛṣṇa left His body and died like us..." There are a party, they think like that, "Kṛṣṇa also died like us." But that is not the fact. Kṛṣṇa left His so-called body just to befool the rascals. Because the rascals are thinking, "Kṛṣṇa is like us," therefore to bewilder them, Kṛṣṇa leaves a māyā body so that they may think that "Kṛṣṇa is like us." But actually here is the secret, that jahau sva-tanvā. He left this world in His original body. He has no such distinction. Śravaṇīya-sat-kathaḥ. If His body is like our body, material body, then what is the use of hearing about His activity? We are interested in the words of Kṛṣṇa. If Kṛṣṇa is like us, He has got the same material body, then why we should be interested to read Bhagavad-gītā, He is also a man like us?
Therefore here it is said, śravaṇīya-sat-kathaḥ. By hearing about Kṛṣṇa, you become liberated. So if He is equally as good as you are, then what is the use of reading His book, reading His instruction? But here it is said, śravaṇīya-sat-kathaḥ, tadāhar apratibuddha-cetasām. These things are spoken by less intelligent class of men, apratibuddha-cetasām. They say, cetasām abhadra-hetuḥ kalir anvavartata: "Because Kṛṣṇa passed away, therefore Kali got the opportunity to enter." That is, to some extent it is fact. But Kṛṣṇa, although left this planet, and if He is everything, how Kṛṣṇa can go away? Kṛṣṇa can remain with you eternally. And even if you say that "Because Kṛṣṇa went away, therefore Kali got the chance of entering," but if you keep yourself with Kṛṣṇa, where is the chance of Kali to enter? Where is the chance? So you keep yourself in Kṛṣṇa consciousness. Kali will not be able to touch you.
