Zelis  to Usbek in Paris
Never was a passion more powerful or more lively than that of Cosrou, a white eunuch,  for my slave Zelide  : he is asking for her in marriage with such fury that I cannot refuse her to him. And why should I oppose it, when her mother does not, and Zelide herself seems satisfied with the thought of this false marriage, and the vain shadow she is being offered ? 
What use can she make of that unfortunate, who will be a husband only in his jealousy, who will cease to be indifferent only to enter into futile despair, will always recall the memory of what he once was to make her remember what he no longer is, who ever willing to give of himself, and never giving, will constantly deceive himself and her, and make himself feel at every moment all the miseries of his condition ?
What would it be to be forever in images and phantoms ? To live only in order to imagine ? To find oneself always surrounded by pleasures and never among them ? Languishing in the arms of an unfortunate not to respond to his sighs, but only to his regrets ?
What contempt must one not have for a man of this kind, whose purpose is only to guard, and never to possess ? I look for love, and do not see it.
I speak freely to you because you like my candor, and prefer my openness and my sensitivity to pleasures to the feigned modesty of my peers.
I have heard you say a thousand times that eunuchs enjoy with women a kind of sensual pleasure that is unknown to us ; that nature compensates itself for its losses ; that it has resources for repairing the handicap of their condition ; that one can indeed cease to be a man without ceasing to be sensitive ; and that in that state one is in something like a third sense, where all you do, so to speak, is to change pleasures.
If that were so I would find Zelide less pitiable ; it is something to live with people less unhappy.
Give me your orders on this matter, and let me know whether you wish the marriage to take place in the seraglio. Adieu.
From the Isfahan seraglio this 5th day of the moon of Chalval 1713
