The fall of the Vedic empire was "from within" from the corrupt lazy weakened selfish Brahmin class due to the influence of Kali-yuga. This also allowed in the increased mundane worship of demigods, and the violent invasion of Islam that killed millions and force coverted millions of Indians to Islam leading to the bogus breakaway states of Pakistan and now Bangladesh. Also the knowledge from the Ayuravedic teachings of Dhanvantari were mostly lost just after Kali-yuga began 5000 years ago.

1920 records at Jagannath Puri Temple reveal the English administration invited Ayurveda Brahmins to perform rituals to get rid of the Spanish Influenza pandemic spreading India in 1918, 102 years sgo 4.

Keep in mind in 1928/20 India's population, that included Pakistan and Bangladesh (East Pakistan) that both never existed until 1947, was just 280 million.

Out of this population, over 20 million died from the Spanish Influenza pandemic virus.

They chanted mantras, burned Cow dung, spread around Ganges water, putting Tulsi leaf on the sick.

Sadly these big pandal programs only spread the virus faster due to big crowds.

It was also revealed many children died of suffocation due burning bonfires of Cow dung that proved to be also useless.

Still 20 million Indians died.

Deaths only started coming down when these religious gatherings were banned and people told to stay in their homes.

In 2020, 100 years later, Prime Minister Modi learned from this and immediately banned religious gatherings and ordered lock down to fight COVID-19.

This act saved millions of Indian lives from COVID-19

In 1918/20 at the request of the English administration, big Ayurveda Brahmins arranged massive kirtans, burnt cow dung, put Tulsi leaf on the sick, spread around Ganges water and chanted many mantras to stop the Spanish Influenza pandemic.

The fact is, according to records at Jagannath Puri Temple, it only made the virus worse because of these big gatherings and eventually over 20 million Indians died.

This is because religious gathering bring hundreds of thousands of people together that only spread the Influenza virus faster.

In fact, many young children also died from breathing difficulties caused by the massive cow dung fires and pollution.

These religious gatherings and Vedic rituals like burning Cow dung, had no effect on stopping the virus regardless of what Vedic text claim, the Cow dung smoke only in fact killed many babies and the elderly.

We have to understand that due to Kali-yuga, the Vedas and their Brahmin teachers who follow them, obviously have lost faith and their mystical potency due to the onslaught of Kali-yuga that has weakened the priestly (Brahmin) class.

And that is why all attempts to help end the Spanish Flu pandemic in 1918/1920 with Vedic mantras.

The violent invasion of the Indian Subcontinent by primitive tribes, converted to Islam from Saudi Arabia and Iran in the 9th Century AD,
killed over 100 million followers of the  Vedas over 1000 years, and converted another 1 billion to Islam.

This only happened because of the corruption and moral weakness from within, from the corrupt Brahmin class that degraded the other three classes,

Kshatriyas,
Vaishyas,
Sudras,

And created a bogus class called Dalits or Harijans (untouchables)

In other words, the fall of the Vedic empire was "from within" from the corrupt weakened selfish Brahmin class.

This also allowed in the increased mundane worship of demigods and the violent invasion of Islam to make in roads.

And the knowledge from the Ayuravedic sastra of Dhanvantari were almost lost just after Kali-yuga began 5000 years ago.

Also lost was also the mystical potency manifested from fire-yugnas and burning sacred cow dung while chanting various powerful mantras.

All become useless long ago, from the time of Buddha 2,500 years ago.

So how was the Spanish influenza defeated in 1920?

Only when the British authorities told everyone to isolate themselves and stay at home, did death numbers drop in India.

That is why Modi banned religious gatherings in March 2020 during COVAD-19 pandemic because they learn from the Spanish Influenza pandemic 100 years before.

And personally because of diabetes, I take the Flu vaccine every year (for 35 years now) and it does protect the biological body and has no side effects with me.

At nearly 70, we must be careful.

Remember 85% of COVID-19 deaths are over 65 year olds.

In 2020 the population on the Indian Subcontinent -

1 -India is 1 billion 480 million
2 - Pakistan is 230 million
3 - Bangladesh 176 million

The following is what future generations of devotees will have to deal with that the present generation in 2020 cannot even imagine WILL be possible.

Other dangerous features of impersonalism in this material World.

Never underestimate the many branches of "Impersonalism" a greatly underestimated reality in the material creation.

Impersonalism has many features we have not yet fully understood in our generation.

In the future, because of advanced technology and artificial intelligence, future generations will see entire cities exist with "material bodies" but none of those "vessels" will have a jiva soul!

Such a reality of materialism (Androids) devoid of the soul is laughed at by the less intelligent, such fools also said heart transplants are not possible.

Yes, even the biological material vessel can be grown (not created as that is not possible) in a laboratory and have no "dominant" jiva soul.

How is this possible?

Simple with the right technology, a machine is built that reacts to the actions of others, needing no person (soul) controlling them.

Such programs already exist on car assembly lines and security in many buildings and spell check devices.

This is not always a bad thing, I talk to my computer every day called "Google Hub"

She controls everything in my house from lights, air conditioning, TV, Blue ray recorder and mobile phone

And she knows everything too even all of Prabhupada's Books word for word.
