Thoughts on an important primary source

From my journals, when I was researching Lifestyles in Early South Asia; both writing and lifestyle notes:

Today was so pleasant and busy that it took until about 4:30 to actually notice I'm sick from a particularly frightful food-available-in-India experience. But other than that the day was wonderful! Lots of work done! [Omg, on a very personal note: I just noticed my youngest granddaughter was born exactly the same day years later, definitely a good day!]

I am really enjoying the big set of ancient writings on architecture -- he's really made a miniature library out of his gazillions of years of hard work: separate volumes of the original Sanskrit critical edition; the actual translation; a compilation of architectural thoughts from other old Indian writings; a book of modern illustrations that are the closest they could think of to the original written descriptions; and an encyclopedia (and its earlier incarnation as a dictionary) of the many technical and I think other architectural ideas in the main work. But so far I'm still in the midst of the many many introductory pages for all these works, so I'll know what I'm doing. Let's hope all this prep is worth it -- but it's fun, so that's fine! Tomorrow I plan on making more certain I'm looking at this in the right time period -- oh dear, if it's like 100 years later I will have to really really change my whole book(s) plan, because the whole idea was to include a work like this as one of my primary sources. I had accepted the translator's date, figuring he knew best, but just an hour ago I finally found his reasoning...and oh dear it does not convince me at all. Of course if it's a bit earlier, or even lots earlier, that's no problem....I'll find what much more recent scholars say... 
I was so very relieved, as reported the next day:

Whew, that date I had for that extremely major primary source is correct, so all can go as planned, as much as it ever does! Actually, I probably checked scholarly specialists for this already for that, years ago. Especially relieved because today is one of India's worst: noise, rabid dogs, insane criminals at the doorstep, basic utilities including main phone and air conditioning not working, etc.
