The Sun and the Firefly
If all the light-emitting animals everywhere in this world
Would, for the purpose of illumination, shed light:
One single ray, issued from the orb of the sun, outshines them all,
And infinitesimal would be all the luster of the hosts of light-emitting animals.
from The Meaning of Purity
This world is attached to the mud of name-and-form.
The wheel of birth-and-death revolves, similar to a wind-wheel. Having cognized the revolving world as like a snare for wild beasts The wise roam about similar to the birds in space.
–Astasahasrika Prajnaparamita (from Chapters V and VIII, respectively)
