I think the song having words "from Sarah with love" is connected with this phrase. As for the origin - there's only one source, nothing, but a loving heart it can be. From Sasha with love!
I love, but rare speak about that. I love, but not for ears, hands, lips, eyes. He's like a merchant of sweet love to make it dead one who exposes his soul with cries. /ll-O6/ll-O, Ho pe}l{e roBopl-O o6 -)moM. /ll-O6/ll-O, Ho He g/l9l MHorux r/la3. mopryem 4yBcmBoM mom, Kmo nepeg cBemoM Bcl-O gywy BblcmaB/l9lem Ha noKa3.

In Russian it is the same one while in English the lines have been changed a lot as I don't remember the original verses of Shakespear. Only very far resembling could be recognized, too far for restoring. Sorry!
I love, but tell about that so rare. I love, but not for so many eyes. One acts like tradesman who is trying in despair to sell sweet loving which exposed, dies.
