Assembly

A thing can only be described
  by its constituent parts. 
A tree is it’s leaves, 
  roots, trunk, and bark... 
I, of mind, body, heart...

And parts themselves but part. 

Where does a thing end, 
Where does it start
When collective  but part
  of still some greater part? 

Between You and I

Harmony rings
When tensioned string
Neither loosely bound
Nor overly wound

Between extremes 
Life and death 
At last breath... 

Polynucleotides bound
In-coiled around,
Helix paired
Macromolecular cipher

... When, mid
Unit of time
Planck defined?

Where all is center
What surrounds?
When all within 
What enters?
