love your eyes, my dear
Their splendid, sparkling fire
When suddenly you raise them so
To cast a swift embracing glance
Like lightning flashing in the sky

But there’s a charm that is greater still:
When my love’s eyes are lowered
When all is fired by passions kiss
And through the downcast lashes
I see the dull flame of desire

F.Tyutchev (translated from Russian by …who knows)
Hear it in Russian in this Tarkovsky film Stalker
