From War and Peace, Book XII, Chapter II

On reaching Moscow after her meeting with Rostóv Princess Mary had found her nephew there with his tutor, and a letter from Prince Andrew giving her instructions how to get to her Aunt Malvíntseva at Vorónezh. That feeling akin to temptation which had tormented her during her father's illness, since his death, and especially since her meeting with Rostóv, was smothered by arrangements for the journey, anxiety about her brother, settling in a new house, meeting new people, and attending to her nephew's eductaion. She was sad. Now, after a month passed in quiet surroundings, she felt more and more deeply the loss of her father, which was associated in her mind with the ruin of Russia. She was agitated and incessantly tortured by the thought of the dangers to which her brother, the only intimate person now remaining to her, was exposed. She was worried too about her nephew's education, for which she had always felt herself incompetent, but in the depths of her soul she felt a peace - a peace arising from consciousness of having stifled those personal dreams and hopes that had been on the point of awaking within her and were related to her meeting with Rostóv.
The day after her party the governor's wife came to see Malvíntseva and, after discussing her plan with the aunt, remarked that though under present circumstances a formal betrothal was, of course, not to be thought of, all the same the young people might be brought together and could get to know one another. Malvíntseva expressed approval, and the governor's wife began to speak of Rostóv in Mary's presence, praising him and telling how he had blushed when Princess Mary's name was mentioned. But Princess Mary experienced a painful rather than a joyful feeling - her mental tranquillity was destroyed, and desires, doubts, self-reproach and hopes re-awoke.
During the two days that elapsed before Rostóv died, Princess Mary continually thought of how she ought to behave to him. First she decided not to come to the drawing-room when he called to see her aunt - that it would not be proper for her, in her deep mourning, to receive visitors; then she thought this would be rude, after what he had done for her; then it occurred to her that her aunt and the governor's wife had intentions concerning herself and Rostóv - their looks and words at times seemed to confirm this supposition; then she told herself that only she, with her sinful nature, could think this of them: they could not forget that situated as she was, while still wearing deep mourning, such matchmaking would be an insult to her and to her father's memory. Assuming that she did go down to see him, Princess Mary imagined the words he would say to her and what she would say to him, and these words sometimes seemed undeservedly cold, and then to mean too much. More than anything she feared lest the confusion she felt might overwhelm her and betray her as soon as she saw him.
But when on Sunday after church the footman announced in the drawing-room that Count Rostóv had called, the princess showed no confusion, only a slight blush suffused her cheeks and her eyes lit up with a new and radiant light.
"You have met him, Aunt?" said she in a calm voice, unable herself to understand that she could be outwardly so calm and natural.
When Rostóv entered the room the princess dropped her eyes for an instant, as if to give the visitor time to greet her aunt, and then just as Nicholas turned to her she raised her head and met his look with shining eyes. With a movement full of dignity and grace she half rose with a smile of pleasure, held out her slender delicate hand to him, and began to speak in a voice in which for the first time new deep womanly notes vibrated. Mademoiselle Bourienne, who was in the drawing-room, looked at Princess Mary in bewildered surprise. Herself a consummate coquette, she could not have manoeuvred better on meeting a man she wished to attract.
"Either black is particularly becoming to her or she really has greatly improved without my having noticed it. And above all, what tact and grace!" thought Mademoiselle Bourienne.
Had Princess Mary been capable of reflection at that moment, she would have been more surprised than Mademoiselle Bourienne at the change that had taken place in herself. From the moment she recognized that dear, loved face, a new life-force took possession of her and compelled her to speak and act apart from her own will. From the time Rostóv entered, her face became suddenly transformed. It was as if a light had been kindled in a carved and painted lantern and the intricate, skilful, artistic work on its sides, that previously seemed dark, coarse, and meaningless, was suddenly shown up in unexpected and striking beauty. For the first time all that pure, spiritual, inward travail through which she had lived appeared on the surface. All her inward labour, her dissatisfaction with herself, her sufferings, her strivings after goodness, her meekness, love, and self-sacrifice - all this now shone in those radiant eyes, in her delicate smile, and in every trait of her gentle face.
Rostóv saw all this as clearly as if he had known her her whole life. He felt that the being before him was quite different from, and better than, any one he had met before, and above all, better than himself.
