What is Aarya dukkha Sacca?
In the Pali suttas, the word "dukkha" is used in three different ways:

(i) Unpleasant/painful feelings, which are not "suffering". Refer to SN 36.6, MN 37, MN 38, MN 148 and countless other suttas that explain "feelings" ("vedana") in themselves are not suffering. 

(ii) The inability of impermanent things to bring true &amp; lasting happiness (refer to SN 22.59), often loosely translated as "unsatisfactoriness", which is not "suffering". Refer to SN 22.1, which clearly explains how change (vipariṇamanti) or impermanence itself is not "suffering". 

(iii) Mental suffering from mental proliferating, which is "suffering". In the 1st noble truth, all "suffering" was summarised as "attachment" ('upadana') to the five aggregates, as follows: "saṃkhittena pañcupādānakkhandhā dukkhā."

In summary, the "Ariya" ("Noble") perspective of what "Dukkha" is refers to "upadana" ("attachment"). It is not related to impermanence. Impermanence only contributes to suffering when impermanence is attached to as "I", "me" &amp; "mine" (again, refer to SN 22.1). 


  He does not assume the body, feelings, perception, mental formations &amp;/or consciousness to be the self, or the self as possessing, or as in the self, or the self
  as in.... He is not seized with the idea that 'I am
  the body... consciousness' or 'the body... consciousness is mine.' As he is not seized with
  these ideas, his body... consciousness changes &amp; alters, but he does not
  fall into sorrow, lamentation, pain, distress or despair over its
  change &amp; alteration.
