I wonder if if we should call "ariya-sacca" Noble Truth or "True Ariya".
Noble Truth implies a kind ot reality in our mind. True Ariya is related to a quality of being Ariyan (a type of people).
I think that it is a simple algebra to substitute "dukkha" with "X": where X may be an issue, a problem, a goal, a project,... And ariya-sacca (principle) is still useful.
