Hi again, and a happy new year to you!
Best of luck with using that phrase as I think it would be unlikely to yield useful results, although you could prove me wrong! Almost all dead language resources I know (which, granted, isn't a lot) use as direct a translation as possible and skip out the nuance of the original word. The example I gave does better translates into "burning of the mind" but its more literal and direct translation is ardour and is what will be used most frequently, hence why I used that example since you'd mentioned that word previously for magic. Considering this, maybe it would be easier to find a single word and try and expand from there? Regardless, I wish you all the best with your search and a satisfactory resolution to it!
