Many finds it difficult to define poetry!
So in your sense, what is poetry to you?

An aid to memory. An experiment into more advanced modes of being. Chronotope turned euchronia. The esemplastic fled away with the quadlibetical. The Transforming Agent of Change. Ostranenie of dull perception. Intelligence distilled into truth.

It's the way I feel about something, or an experience I have had or something I have noticed.
It's a move of the Spirit that brings me to need to say something.
It's a weeping or dying on the page.
Poetry lets me get it out in a way that doesn't require sources, or proof, or explanation. It just is.

Poetry to me is like a moments capture in our heads and express in words thoughts our hearts
