With the end of this Kaliyuga, this eon (Manvantara) would end and after a break, a new one will begin.
Though I understand scholars have tried to calculate the date; what I understood from the Kalki Purana, is that when Kalki comes to vanquish Adharma personified, and bring in Satya Yuga, there is a fire that removes it after the Final Battle - This same timeline I was told by the Source of reality at 15, and is recorded similarly in Zoroastrian, Biblical, Islamic texts, etc.
The planet is dying, so this idea of hundreds of more years isn't viable; as we're at an accelerated rate of destruction, that needs addressing for any to survive.
What I saw at 15, was that there is a Quantum Fire that will cleanse here, as the Final Battle takes place, and then after the Enlightened Saints are resurrected into a restored "Eden"; this idea I believe is recorded the same in the Kalki Purana, as we come into an age of Enlightenment (Satya Yuga).
I'd love to teach people enlightenment, and to show what it means to be Dharmic; yet the world won't listen properly, as it has already fallen into degradation as stated.
1:28 In Kah-yuga, a person with a lot of money will naturally be respected as a great soul. If a twice-born person earns his livelihood by lending money on interest, he will be considered a pillar of society. The sannydsls of Kah-yuga will be attached to home and property, and householders will become devoid of all power of discrimination. In Kah-yuga, people will blaspheme a spiritual master or other elderly person without hesitation. Indeed, people in general will simply become hypocrites, liars, and cheaters
2:28 The four exalted brahmanas offered their obeisances unto Lord Visnu, who had assumed the form of a human being. They very well understood that Lord Kalki had appeared to rid the earth of all those who had become degraded to the level of sinful demons.
there will be many hundreds more. 'End of times' according to Hindu mythology
The terminology "End Times" Biblically was the end of this Age (Aeon) of Ungodliness, where in my understanding the Messiah (Sananda) returns before the Judgement Day Fire, and then the Messianic Age.
This is recorded the same in Zoroastrianism where
Frashokereti (Judgement Day Fire), means 'making wonderful/excellent' - with the Saoshyant coming before it exegeting (
Zand) the religious text.
In my understanding Kalki/Skanda brings in Satya Yuga, where I believe in the Bhagavad Gita it says Skanda comes as the final utterance before Mahapralaya.
I find part of the problem with defining Hinduism ideologies separate to the rest, is that it is all one reality, with One Source, and it communicated these ideas globally the same, then people have chosen to differentiate, which means they don't see the bigger picture is all part of the same contexts - Sort of like a jigsaw, where we need to put the puzzle together, to understand all the details properly.
In my opinion.
