Full of constraints.

This life is full of constraint

It need to interact

It needs many inputs

natural inputs,social inputs

retrieve-store and expend energy

That with a perfect balance

unlike steam engine where

coal burned to boil water

And steam generated to move

piston and machine attached

ROARS ,CHUG

The being consume energy

to chug to move to pull on

And beams a glow to

Soul and souls of soul to

zoom,magnify.
