Commentary
Part Three: Kagero

 Kaoru's reply. Even he, he says, who has seen impermanence so often, does not grieve where it can be noticed, and so states his way of keeping sorrow out of sight. In fact he went on thinking of Ukifune, and the gap between what he feels and what he says is what makes him the man he is. After this exchange the Eight Lectures on the Lotus Sutra were held at Rokujo in memory of Murasaki.

 Tsune nashi is that nothing lasts. Kokora is so much, over so long a time. Uki mi is a wretched self, said in self-deprecation. Nageki ya wa suru is a rhetorical question: he does not grieve so. He receives her sympathy without acknowledging it directly, and the habit of never showing feeling holds here too.
