Limits of reality, or: Word fish

My first bagua poem

rim where water licks surface air above rim
side invisible but known existence only this side
cornered word fish always turns to next corner
edges clear to big shapes peering through edges

side through which small sails visible before side
edging in through hollow plastic hull near edge
corner plant stiff and also in another corner
bottom covered by many colors all over bottom

My friend Suzette introduced me to the bagua form of poetry so, of course, I had to give it a go!
