How Aomame got pregnant?
Sex in the novel describes the mystic experience. The way Murakami narrate that whole night with lightening and thunder after which Aomame got pregnant is just a symbolic representation. After that night Aomame and Dowager lost their anger. Only explanation to that could be the mystic experience. As Fuka Eri had said it was a process of purification. But this night is still a mystery to me as well as all readers. But as far the question of morality is concerned I found it very strange to use rape of 10year old girl as a metaphor.
The two women died in same circumstances. That could be just a coincidence. After smoking hashish Kumi Adachi said she had died once and then she reborn. Then Tengo asked her:
“why did you die?”
So that I would be reborn like this.
Then she told him that she was reborn for someone else.
“ The biggest problem is when it comes to being reborn is that
people aren’t reborn for their own sakes. They can only do it
for someone else.”
Then she advised Tengo to leave before exit is blocked. May be she was Tengo’s mother who was reborn for Tengo once again. She also helped Tengo for his father’s last rituals.
