Domanassa & Dukkha in enlightened beings? What is the difference between domanassa &amp; dukkha? Does domanassa arise in enlightened beings? Does bodily dukkha arise in enlightened beings?
OP: What is the difference between domanassa &amp; dukkha?

There are many classifications of feelings:

Vedanā (Feeling)
According to the 5-fold classification, a distinction is made between mental and physical pain and pleasure.

Vedanā (Feeling)
In this classification, physical pain (Kāyika dukkha) is called simply dukkha and mental pain (cetasika dukkha) is called domanassa. Kāyika dukkha and cetasika dukkha are also dukkha, hence classified as such in 3 fold classification.

Dukkha - General Application, &amp; various views regarding dukkha. As simple sensation (: pain) &amp; related to other terms: (a) principally a vedanā, sensation, in particular belonging to the body (kāyika), or physical pain (opp. cetasika dukkha mental ill: see domanassa).
Domanassa - Domanassa means unpleasant feeling in mind. lit. 'sad-mindedness', grief, i.e. mentally painful feeling (cetasika-vedanā), is one of the 5 feelings (vedanā, q.v.)
OP: Does domanassa arise in enlightened beings?

No. An enlightened person feels Dukkha (Kāyika dukkha) but not Domanassa:

Bhikshus, when the instructed noble disciple is touched by a painful feeling, he does not sorrow,
or grieve, or lament, or beat his breast, or become confused. So he feels (only) one feeling: the bodily, not
the mental.
