the bird chirps, flapping
its wings to soar.
it's sole purpose living
each day, breathing and
eating for survival.
the bird lives simply.

the trees stand tall
as roots dig deeper,
grounded. leaves appear
in cycles contributing to the
intake and release of nourishment.
the tree lives simply.

the human wakes with many
contemplations, desires, goals.
numerous expectations all
constructed from illusions.
a definitive role continuously changing.
the human lives complexly.

What changed?
