stability is imagined by the mind
by tangents concentrics lines
feeble green static splines
though initial conditions ill defined

subtle wishes to switch positions
find parallels perpendicular
coincidence broken in purple
essential diagrams stranded
adjusted spans saddle busted
riding off into impossible turf

but what is reference is set in stone
guidance by first principle tomes
vestigial recollections
stable under what went wrong
a ready scaffold for new practicals
