Disharmony or harmony among humans is relative to the collective

Health = Harmony.
Disease = Disharmony.
Harmony or disharmony, health or disease, is wrt. the collective.
Being under or over the collective is going to create:
isolation, alienation, separation, disease, disharmony, pain, suffering etc.

# If you are a hellish creature in hell = You are in harmony.
# If you are a heavenly creature in heaven = You are in harmony.
# If you are a heavenly creature in hell = You are in disharmony.
# If you are a hellish creature in heaven = You are in disharmony.

That is why the regressives and progressives hang out together sometimes.
That is because they both have the commonality of being outcasts and out of tune with the collective.

Also there is social harmony vs. existential harmony.
Society may not be in harmony with existence.
That would create the collective suffering.
But you may be in harmony within society.

Conversely, you may be in existential harmony if you are enlightened, but be in disharmony with society.
If you are stronger than society, you will transform it.
If you are weaker than society, it will oppress you.
