Human life alone permits choosing between heaven, hell, or liberation through the intelligence to practice Krishna consciousness.Listen — Srila Prabhupada Uvaca
Prabhupāda: Śrīmad-Bhāgavatam, Canto Six, Chapter One, verse number twenty? Is that the number, twenty? [leads devotees in chanting] [01:52] atra codāharantīmam itihāsaṁ purātanam dūtānāṁ viṣṇu-yamayoḥ saṁvādas taṁ nibodha me [SB 6.1.20] "In this regard, learned scholars and saintly persons describe a very old historical incident involving a discussion between the order-carriers of Lord Viṣṇu and those of Yamarāja. Please hear of this from me." So Yamarāja is the superintendent, or the judge, for considering what kind of punishment should be given to a certain sinful person.
After death, those who are sinful, they are taken to Yamarāja for judgment, what kind of punishment one has to be given. And those who are pious devotees, they are taken charge by the Viṣṇudūta. I think the Christian doctrine, that in this life either you go to hell or go to heaven. Is it not? Devotee: Yes. Prabhupāda: That is nice.
The same thing. This human form of life is a chance. Actually, in this material world we are all suffering. Duḥkhālayam aśāśvatam [Bg 8.15].
You cannot make it a happy place. That is not possible. Kṛṣṇa says, who has created this material world, He says, duḥkhālayam aśāśvatam. Duḥkha means unhappiness; ālayam means place.
Duḥkhālayam aśāśvatam. That is also temporary. Duḥkhālayam aśāśvatam, nāpnuvanti mahātmānāṁ saṁsiddhiṁ paramāṁ gatāḥ [Bg 8.15]. So this is place of duḥkhālayam.
Any commonsense man can understand that Kṛṣṇa says in the Bhagavad-gītā... We may challenge, "Where is the unhappiness? We are very happy." Madmen. Kṛṣṇa points out, "No, it is not place of happiness." Why it is not place of happiness?
Now, janma-mṛtyu-jarā vyādhi-duḥkha-dośānudarśanam [Bg 13.9]. Why don't you see the real unhappiness? This is real duḥkha, or unhappiness. What is that? Janma-mṛtyu-jarā-vyādhi.
