I am continuing to think about Unity, the bringing together of parts to create a whole.
Here are a few look-ups that are helping me with that.

From the dictionary:
unity |ˈyo͞onətē|  noun
1 the state of being united or joined as a whole:  their leaders called for unity between opposing factions.
• the state of forming a complete and pleasing whole, especially in an artistic context: the repeated phrase gives the piece unity and cohesion.
• a thing forming a complex whole: they speak of the three parts as a unity.
ORIGIN Middle English: from Old French unite, from Latin unitas, from unus ‘one.’

From the thesaurus:

2 unity between alliance members: harmony, accord, cooperation, collaboration, agreement, consensus, solidarity; formal concord, concordance. ANTONYMS strife, discord.
