These look like titles of books. If you can find no standard translations, perhaps you could just translate them literally. I don’t translate Buddhist texts, so this is a pretty much just a very wild guess.
Literally:
奥意金匙: The golden key to the deep meaning(s) (or meanings of the deep mystery/mysteries)
奥意: Deep meaning(s), meaning(s) of the deep mystery/mysteries
金匙: Golden key
上: First volume (or Part 1 of an article)
下: Second volume (or last volume of a multi-volume work; or Part 2) |
