It has to do with Rajiv Malhotra's term "History centricism". Indian religions aren't history centric while Abrahmic religions are dominantly so
eg. Holkar screwed up on Panipat (Whole Najib affair) is a fact. Now Holkar is also Dhangar hero. So one who criticizes Holkar, earns wrath of Dhangars
Should they be taught of history so that they don’t repeat mistakes? Yes
Do we need to teach them history as it is? Are events important or are the lessons important? Lessons in my opinion.
A construct like panchatantra where fox lion and hyena had a battle and a fox made deal with hyena calling him a “manasputra” thereby leading to defeat
But most of that work was done by evading taxes (many letters by Madhavrao available which threatens her to pay up or else...)
We know her temple rebuilding is monumental work for Hindu civilization
I am appreciating varNa-vyavasthaa more and more. I see the point. It is difficult (nay almost impossible) to implement it in these changed times. So not advocating it
But I begun seeing its point for past few years
It is a fascinating story which underlines how a "Hindu" views at its past and smooths the rough edges
Mahadev got pleased and told them to ask for any boon. If my memory serves me correctly, A'zeb asked for power and Shivaji asked for dharma
Aurangzeb got power and Shivaji got to establish dharma on this earth - thus boon given to both by Shankara fructified.
If left alone, it will smoothen all the rough edges of memory that Hindus have for Muslim atrocities. This is written when Muslims were defeated conclusively and Hindus emerged victorious after 27 year war.
There is a profound wisdom in Hindu Historiography - and it is used by Indologists to criticize Hindus : That Hindus do not maintain historical records
Before that Deepavamsha and Mahaavamsha are Buddhist historical records during Ashoka's time which pass Indological test.
Records like these (which pass modern Indological or Historiographical tests as "authentic history") sets the narrative in stone. It cannot be altered by anyone without perpetual misgivings.
In India, caste-clan-family is very much alive and thriving. It is anathema to Indian setting.
But they were wise enough not to make it publicly available (in all its grey shades) and make the narrative set in stone.
Finer details - are irrelevant for real purpose.
The real purpose is - sustenance of "dharma".
