Differences

There are no differences but differences of degree 

between different degrees of difference and no difference.
-William James

Once you transcend the external differences,

anything can be merged with anything.

-Liezi

To direct the mental current towards the basic unity of all things
and to divert it from the observation of differences is 'observance';
therein lies transcendent bliss.
-Tejo-bindu Upanishad
