Taijitu, the Taoist symbol of equilibrium between yin and yang
A tree too big to embrace
is born from a slender shoot.
A nine-story tower
rises from a pile of earth.
A three thousand mile journey
begins with a single step.
... do not grasp greedily
and so do not lose.
...a rush for success will fail.
Proceed at the end as at the beginning...
the wise let all things develop naturally.
-- Tao Te Ching 64 by Lao Tzu
-- Excerpts from Yibaishiba jie, The 180 commandments
