"Teach us to care and not to care / Teach us to sit still." (T.S Eliot, from Ash Wednesday )
... words I should have contemplated more, in many contexts.....

Keeping Things Whole

In a field
I am the absence
of field.
This is
always the case.
Wherever I am
I am what is missing.

When I walk
I part the air
and always
the air moves in
to fill the spaces
where my body's been.

We all have reasons
for moving.
I move
to keep things whole.

-- Mark Strand, 1964
