So the reflection of Absolute Being
can be viewed in the mirror of Not-Being,
for nonexistence, being opposite Reality,
instantly catches its reflection.

Know the world from end to end is a mirror;
in each atom a hundred suns are concealed.
If you pierce the heart of a single drop of water,
from it will flow a hundred clear oceans;
if you look intently at each speck of dust,
in it you will see a thousand beings.
A gnat in its limbs is like an elephant;
in name a drop of water resembles the Nile.
In the heart of a barleycorn is stored a hundred harvests.
Within a millet-seed a world exists.
In an insects wing is an ocean of life.
A heaven is concealed in the pupil of an eye.
The core at the center of the heart is small,
yet the Lord of both worlds will enter there.

~ Mahmud Shabistari (Persian Sufi poet 14th c.)
