Polarity

Nay, why reproach each other, be unkind,
For there's no plane on which we two may meet?
Let's both forgive, forget, for both were blind,
And life is of a day, and time is fleet.

And I am fire, swift to flame and burn,
Melting with elements high overhead,
While you are water in an earthly urn,
All pure, but heavy, and of hue like lead.
