There are two scenes in this chapter I find "extreme" but in different ways.
The first is straight-forward and depicts Genji's very intense feelings for Fujitsubo. He can hardly control himself saying, strikingly, at one point "I would gladly die of shame than have you hear I am still alive" (Tyler 204)(世の中にありと聞こしめされむもいと恥づかしければ、やがて亡せはべりなんも、)
The second puzzles me. Rokujō is the murderess of his wife Aoi and when this fact is kept in mind, his conversation with her, his attraction to her, and his attraction to her daughter, all seem odd to me, in that he (or the narrator) seems to be able to put this fact behind him.
Part of me thinks that perhaps principle ("Do not love the person who killed someone you loved") or literary psychological realism ("In X situation, Genji should think/feel ...") should not be the primary reading element here.
One might consider reading it more situationally: Aoi is dead, there is nothing that can be done about that, and here is the woman who loved him so much that she engaged in a desperate — granted not well chosen but certainly passionate — act to draw him to her. Could Genji simply be drawn to her fire for him when he goes to see her? It is a complicated affair, and very interesting to turn over in one's mind.
Or one might think that Murasaki, rather than being primarily interested in realism, selects a lyrical, specific aspect of the situation, and wants most to explore only that.
Also we can keep in mind that Genji is almost never angry about anything.
... And yet, the narrator does say in Chapter 12 "Suma" that his "unfortunate" or "sad" (うし) attitude about her with regard to Aoi was "mistaken" (一ふしうしと思ひきこえし心あやまりに、 NKBZ 2:186).
I asked a student of mine, Pooja Jajodia, a young women whom I consider to be a careful thinker, and who has written a novel, to think this chapter over and send me comments. I wanted a woman's considered opinion since I feel that part of my conundrum on this point could be gender based. I'm including her response:
Lady Rokujo and Genji's relationship pre-exists before the novel like a
man's relationship with his karma exists before a birth. Considering the
tension throughout their relationship, especially after Rokujo kills Aoi,
I thought Genji might be fascinated/horrified with the karmic bond that
ties him to Rokujo. He may wonder what sins he committed in a earlier life
that now ties her to him, and it's the possible intensity of these sins
that draws him to her.
There's also the danger of being involved with her. Genji is drawn to
competition and reputation. He cannot see Fujitsubo or Rokujo as closely
as he would a woman of lower social ranking, so his feelings stem from
thrill of being close to "forbidden" women and his own image of what they
look like. ...
As you had mentioned, I thought it was the intensity of Rokujo's
personality that draws Genji to her. I imagine Rokujo as a void everyone
falls into because they they cannot know her any other way.
When Genji witnesses Rokujo's spirit beseeching him for his affection
through a weak, and pregnant Aoi, he realizes how deeply she loves him. Or
loving him to the extent that she becomes possessive. Aoi on the other
hand is never outwardly possessive. She hardly calls on Genji for his
wandering eye and it's this frozen demeanor that makes her inhuman,
unapproachable. Genji is uncomfortable in her presence as he prefers
delicate and weaker-willed women. We weren't assigned the reading for
this, but later in the novel when there's a thunderstorm, the Akashi Lady
doesn't rush to Genji for comfort - in fact she's the only one who remains
calm in the Rokujo Manor - which bothers him immensely. I'm imagining it's
the same thing for Aoi as Genji wants to be dominant in his relationships.
Rokujo is an interesting case in that she's contradictory. She allows him
to feel strong by being in control of her emotions, but on the other hand
reminds him of his human weakness by allowing her spirit to haunt him.
This deception alone is alluring.
Or: Considering how his wife is indifferent and Fujitsubo has no choice
but to be indifferent, Genji takes solace in Rokujo in that she's a woman
of power but isn't indifferent. She may be possessive in a horrific way,
but the sincerity behind her actions is touching. Rokujo could be a
substitute for Aoi and Fujitsubo, which puts her on a different level than
Murasaki who was only a substitute for Fujitsubo. But Fujitsubo started
out as a substitute for the Kokiden Lady, in different respects for Genji
and his father of course.....but I'm not going to get into that.
Now getting onto the heart of the matter: why he goes to Rokujo after Aoi
dies. Genji saw the manifestation of Rokujo's soul in Aoi. For a woman of
such beauty and dignity, seeing Rokujo violent and vulnerable is
unnerving. He goes to her see if she physically manifests this violence;
to see her again in a different light if you may. It's like how people on
the street stop to look at a traffic accident: they want to see the
damage. Genji is curious about the damage he's caused and wants to see it
in physical form. Shikibu notes how distressed he is when Rokujo leaves,
so there's an element of humility in his curiosity. He goes to her not
only because he's drawn to her possessiveness, or her rank/reputation, but
because he's also guilty. Her sadness is powerful.
One becomes more intimate with someone when they see them in their most
vulnerable state. Rokujo was in her most vulnerable state as a wandering
spirit; for her ranking, revealing herself this way may be equal to coming
before a man. Catching a glimpse of her this way is as if seeing her
through her blinds: temporary, but intense.
There's also the thrill of being close to someone so dangerous. Or less
dramatically, perhaps Genji is afraid. Going to her would soften her
violent feelings so he could avoid confronting her spirit again, but of
course this isn't the case.
Even less dramatically, perhaps he goes out of social obligation. But that
cannot be the reason alone. It's part of why he visits her after Aoi dies,
but it lurks behind the larger attraction Genji feels towards Rokujo.
I might add that centuries later the Noh play "Nonomiya" — which takes as its scene the visit of Genji to the departing Rokujō when she is staying at Nonomiya with her daughter undergoing purification before continuing on to the Ise Shrine — also focuses on Rokujō's lonely longing and the shame she incurs from the carriage confrontation at the Kamo festival described in Chapter 9 "Aoi." Genji's frame of mind is entirely irrelevant to this play except that he is described as deeply affectionate (わりなくも), and "noble and sensitive" (情をかけてさまざまの、言葉の露) (Varley translation in Keene's 20 Plays) for traveling to see her.
Rokujō is indeed mysterious. Enchi Fumiko (Masks and in essays on Genji published elsewhere) has accurately observed that Rokujō's origins in the story are hidden in a way that other women's are not. We are given some details of her past in this chapter: she entered service as a consort to the crown prince (brother of Genji's father) when she was 16 and that prince died when she was 20. Since she is 7 years older than Genji, he was at court when she was consort, but we hear nothing of it. In some ways, Rokujō arrives to this story in a disembodied, ghostlike way. (Also: the death of Yūgao may or not be by her hand.)
