Any work of art is multi layered. It works both on the artist's side and the spectator/hearer/reader's side.
There's the abstract idea that it's "about."
There are the clues that present the idea/s.
There are the things the artist intended to show us, and the things the artist included that may have been accidental.
There is the observer's own conditioned or reasoned or instinctive response or intellectual interpretation, which is overlaid on the previous list.
Your writing task now is:
to construct a piece that is "about" an abstract idea, but to write about it entirely by example, showing us, not telling us, using concrete terms throughout. EG: show us happiness, or submission, or anger, but without mentioning the abstract at all.
Don't tell us what the abstract noun/idea is, don't title the piece with it, but let us guess what we think it is, when your first draft is posted.
Any other ideas are fine of course, especially if the image files I presented get you going.
