Heartfelt teacher of little words

The spirit of a teacher:
who was once lost,
Teaches, a great deal
Of broken wisdom
That sheds light;  
Upon kingdoms
Freedoms
Reasons
Seasons
With hindsight  
gained through blindsided views  
Yet gathered with truthful tears
with salty smears of mascara
Cascading discernment
Finally learned  
Earned
Understanding
The hard way.
He is the potter,
and she the clay.
