Srila Prabhupada - "Hare Krsna will finish up in 10,000 years."

Allen Ginsberg - "Will people still be chanting Hare Krsna in 400,000 years?"

Srila Prabhupada - "No, Hare Krsna will be finished within ten thousand years. There will be no more Hare Krsna".

Allen Ginsberg - "Ah. So what will be left?"

Srila Prabhupada - "Nothing. I'll kill you and eat you, and you shall kill me. You shall eat me. That will be left".

Allen Ginsberg - "After ten thousand years?"

Srila Prabhupada - "Yes, there will be no grain, no milk, no sugar, no fruit. So I will have to eat you, and you will have to eat me. Full facility for meat-eating, yes, full facility. 

Krsna is very kind. He'll give you facility - "All right, why just cows and calves? You will take your own son and eat! Yes, eat nicely just like serpents and snakes eat their own offspring and also tigers do the same. 

So this will happen after 10,000 years. And there will be no brain then to understand God (Krsna), no preachers, nothing. And then Krsna will come as Kalki Avatar - "All right, let Me kill you all so that you will be saved." (May 13, 1969, Columbus, Ohio United States)

Keep in mind Lord Krsna Caitanya Mahaprabhu's Sankirtan Moment only comes to one Kali-yuga out of every 1000, or just "once" in a day of Brahma which is every 8 billion 640 million human years.

This Kali-yuga we are in now is very, very rare because of Lord Caitanya's appearance 536 years ago in Bengal India. 

So it is best to surrender to Krsna and His genuine pure devotee now, otherwise it is possible to keep taking birth after birth for thousands of years in this degraded Kali-yuga and sadly be there to see the end of Hare Krsna on this planet.

It is now the time to go back home back to Godhead to our real perpetual home in Vaikuntha or Goloka-Vrindavana.

The material decaying creation is not our real home and we are not these material bodily vessels we are now trapped in.

Although there will be a Golden age of Lord Caitanya Mahaprabhu's Sankirtan movement starting soon or has already begun

However, after 10,000 years that the Golden Age of Hare Krsna will be finished and no more Hare Krsna for the remainder of Kali-yuga.

This means that after the next 10,000 years there will be no more religious principles or morality in the remainder of Kali-yuga.

How to understand this is as follows-

Presently we are 5000 years into Kali-yuga (from 432,000 years of Kali-yuga)

That means there is 427,000 years left which includes the 10,000 years of Hare Krsna.

Then after that, there are 417,000 years left where no Hare Krsna or religious principles will exist.

This further means for the remaining 417,000 years of Kali-yuga, this earth planet becomes a hellish planet.

And then at the end of Kali-yuga, Kalki Avatar comes and kills every one, liberating the trapped jiva-souls from their Kali-yuga hell.

Those jiva-souls He liberates from their degraded material body, enter the impersonal Brahman or Brahmajyoti, and remain there in a dormant state for a very, very long time.

Eventually those jiva-souls fall from there and again take birth in the material creation starting a new beginning, another chance to get out of this material creation and return home, back to Godhead.

The jiva-souls in the impersonal Brahmajyoti cannot remain dormant forever there because the inherent nature of each individual jiva-soul is to be always "active" and not "inactive."

Sadly, some jiva-souls stay dormant in the impersonal Brahmajyoti for so long that when they fall from there, they foolishly believe the impersonal Brahmajyoti is their origin. 

This is due to long, long, long ago forgetting they originated the personal past time of Visnu and Krsna from Vaikuntha and Goloka-Vrindavana.

Therefore because the dormant condition of the jiva-souls in the impersonal Brahmajyoti is temporary, means the jiva-souls must eventually again take birth in the material creation, and carry on attempting to satisfy their independent desires without Krsna.

Spiritual education under the guidance of a bonafide Spiritual Master is the key to progress on the spiritual path.

The fact is, this material world is not our home, and that this material energy is always in a state of constant maintenance, decay and decline and eventually rots away, but we (the jiva-souls) are not these decaying rotting smelly material bodily coverings.

Everyone should try and understand these important points because they are explaining the truth about this temporary decaying material creation we are presently trapped in, and foolishly trying to make our home.

Modern technological atheistic society are attempting to build the Kingdom of God without God however, all their endeavours will fail because the nature of this material universe is it is in a constant state of decline, decay and repeated birth and death. 

As said above, this material creation is not out real home and these gross material decaying bodies we are passengers in, are not our real bodily identity and who we really are in the perpetual spiritual world.

The goal of this rare human species is to use this body in a way that helps us find our freedom from material energy and these troublesome material bodily vessels we are presently confined too, and return back home back to Godhead.^^^.
