The sound of true love
vibrates so high that eventually,
it breaks all the glass
around hearts
And shatters the silence
An outburst of one song
sung in two hearts
A symphony of truth
A fountain of harmonic love
that no longer can be muted

I love this short piece with the expression and indeed a definition of pure love.
I really like the lines
‘An outburst of one song
sung in two hearts’
A lovely variation on two hearts becoming one, or two souls. Some time ago in years passed I recall using the opposite, an idea that some wavelengths are so long they are never lost and so low that nobody hears them, but the wave still travels. It was my idea of a silent love that flowed, you could not hear it, but it is always there and never lost.
