Of course then, typically, knowing that translations of things vary, I’d want to try to isolate the Pali phrase (which, incidentally, is why I still continue to plead with the devas to look favourably on the sticky settings feature request), but as it’s such a short list here, maybe it’s okay to leave it at that. 
Oh and,
