A Clear Image of Itself

I play with this trivial
And highly monotonous
Heptasyllabic poem form
That I like, sort of a cross
Between Japanese choka,
Zoroastrian gatha,
And Shakespearean sonnet.

It's too small to mean too much,
Too capacious to be true,
Too regular to be brave,
Too loose to be demanding,
Too tidy to be memoir,
Too daily to be profound,
Too declarative to be
