Yin Yang

A layer of black,
a layer of blackish-grey,
a layer of grey,
a layer of greyish-white,
and a layer of white
conceal the beautiful blue sky
from the naked eye.

The black gets grey;
the grey gets white;
it 's all finally blue
when you reach that height.

See outside,
seek inside
the prevading Blue;
reveals none but thy self.
