Occasionally a small toroidal vortex
forms in the heart’s left ventricle
when a jet of blood enters it just so.
It is a recorded phenomenon.
The vortex travels smoothly through
its neighboring blood (its poloidal spin
functioning like a wheel) until
faced with the pressure
of an obstructing heart wall
or the aorta’s pulse. Some days
Dyson feels like the toroidal heart vortex,
constrained by a body, informally
colliding with his conviction
of time. Brief are his frictionless
instances floating through something.
He would capture them if he could.
