Beans or stones
from parts unknown,
sand grooves
to wire slides in
frames of bamboo;
place value a priori
to Arabic-Hindu,
O dusty board
of grid-crossed lines:
arithmetical abaci
exchange numbers
across parallel bones
connecting Earth
and Heaven in
chakra spines,
living fossils of
core functions of
mathematics
revealed manually.
