Tabula Rasa (Tides)

I'm taking a creative writing class this semester, and this poem was edited in a workshop with my class. I originally named it "Tides," but people thought "Tabula Rasa" jumped out enough to be a title. What do you think?

"Tides (Tabula Rasa)"

Their meetings came in tides
Controlled by the turning of the moon
(Though they did not know it)

The first stroke of sea on sand
Alone in a city for the sake of
Music?
But he sees her and he knows her
And she does not know
That she is not just a particle in the sea.

The waves wash away, revealing

A glimmer she did not see before

A shell she did not even know she was in

But even the footprints fill themselves in

And the sand becomes a

Tabula Rasa

Leaving no proof behind

High tension

Sparks

(Not enough to light a fire

But still enlightening)

And she tries to swim

But there is nothing to swim in

It is all in her head

He is all in her head, the Sirens croon

The denial of parting

And even though there is a light

Ambiguity fogs the mind

The words are too hard to choke out

so she stays out of the water

Tales of riptides racing through her brain

They say the ocean is rising

But I think that it is falling.
