Dig Deep Enough

So much I think I know,
but I really don't.

I walk to work, the sun is rising.
I walk home, it is setting.

Morning, in the east.
Evening, in the west.

But it's not the sun that moves.
Spinning earth turns toward the sun,
and then away.

I know this, but I don't know it.
It isn't how it feels.

In this regular cycle of days,
the moon floats presenting its own changing face.

Sometimes rising with the sun,
shining bright in the morning and still bright at night.

Other days hanging dark overhead
even as sunlight floods the earth all around me.

On my walk to work this morning,
under a bright moon and the breaking dawn,
I put this question in the stewpot of my mind,
and refused to take the lid off until the solution was done.

Until I truly understood.

Nearly six decades of observing these cycles,
I pushed past superficial understanding,
into at least a slightly deeper knowing.

What a challenge it is
to perceive that the sun in the west
has not moved since it was to the east in morning.

The sun to my left as I walk to work
is in the same place
as the sun to my left as I walk home.

It appears to move because I am on the
Merry-Go-Round of Earth.

The moon is bright when it loops
farthest behind the Earth,
and dark when it is between Earth and Sun.

So simple.
So easy to understand once I allowed my mind
to accept the Sun fixed in its place,
and to understand my perceptions
of movement in the heavens above as -

Illusion:

The mistake of thinking that because I cannot feel
the spinning of the Earth,
that I am, in actuality, standing still.

Dig deep enough, and
every thing I think I know,

I really don't.
