The Alchemy of poetry

How does one write a poem?
The alchemy.
Emotions aren't manufactured.
They come out,
oozing,
bubbling,
haphazard.

Its their streamlining,
its the shoring and streaming,
and a poem is made,thus.
Everything, but poetry
is contrived.
Its got no concoction.
Its the pattern out of incoherence.
