selfless, sacrificial love

I found this while Stumbling across the web... it's beautiful. And it's a sentiment with which I can identify...

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 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 fragrance,
risen darkly 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 and I fall asleep.

-Pablo Neruda

Does anyone... CAN anyone truly love like this?
