What is the theme of this poem?

Your love flows through my veins
like the Nile River flows through
the sands of Eygpt.
Love flows through my veins
like rivers that break off into endless streams
and water the gardens of the green stems
of torn covered rose bushes.

In my veins, you flow, as a sparrow
flies through the blue skies in beauty.
You are the blood that flows through my veins
and later settles deep in my heart
and embraces me with a hug of intimace.

Love flows through my veins
like endless notes played by the sweetest composer
along with his private orchestra playing a lovely melody.
Rivers, streams break off and flow into lakes and oceans,
Like my veins that lead to my heart,
you are always there flowing through my veins.
Your love flows through my veins.
