< The Way that can be told of is not the eternal Way;

< The name that can be named is not the eternal name.

< The Nameless is the origin of Heaven and Earth;

< The named is the mother of all things.

< 

< Therefore let there always be non-being,

<   so we may see their subtlety,

< And let there always be being,

<   so we may see their result.

< The two are the same,

< But after they are produced,

<   they have different names.
