I do not love you as if you were brine-rose,topaz.

I were watching 'Patch Adams' Movie last nite.
Been watching it for times and always shed my tears when i heard Patch reading a part of Pablo Neruda's 17th Sonnet to Carin, her beloved one, in her graveyard
The part that i like the most is the bolded one with different text colour below...

I do not love you as if you were salt-rose, or topaz,
or the arrow of carnations the fire shoots off.
I love you as certain dark things are to be loved,
in secret, between the shadow and the soul.

I love you as the plant that never blooms
but carries in itself the light of hidden flowers;
thanks to your love a certain solid fragrance,
risen from the earth, lives darkly in my body.
I love you without knowing how, or when, or from where.
I love you straightforwardly, without complexities or pride;
so I love you because I know no other way than this
where I does not exist, nor you,
so close that your hand on my chest is my hand,
so close that your eyes close as I fall asleep.
