The video doesn't show that part of the textbook. I found some pages from the series but they're pretty innocuous. [1]
But it's probably accurate. It's not a history textbook but a literature textbook for primary school students. It was probably meant to be used in Hindi classes. So this kind of bullshit would fly under the guise of "it's just a story". [2]
[1]: hxxps://www.exoticindiaart.com/book/details/lamps-of-inspiration-set-of-4-volumes-NZE671/ The "Look Inside the Book" section. The first few pages are just a preface talking about how the book has collected tales to bolster moral values and duties in the reader. Then there are a bunch of contents pages.
The third contents page does match the two short scenes from the video that show the titles of the stories - "8. Nirlobh adarsh jivan" and "17. Parishram ka koi vikalp nahin" (though the latter in the video is titled "Parishram ka vikalp...", no "koi").
So presumably this is the contents page for Prernadeep 3. I can't tell just from the contents page which story might be the one in question, though. The video says it's on page 22 but the contents page doesn't have page numbers. It might be #36 - "Bahin, ham bhaaratiya hain" "Sister, we are Indian" - or #53 perhaps - "Kya aapne ishvar ko dekha hai?" "Have you ever laid eyes on God" ?
The last page has one story and the start of another one (listed in the very first contents page, so preumably from Prernadeep 1 rather than 3), but they're pretty innocuous.
[2]: The larger context around that story is even more amusing, because it's being "told" by Dr Radhakrishnan (President in the 50s and well-known for liking teachers; his birthday is celebrated as "Teacher's Day") to a white person who claims to be very "close to God".
