Commentary
68 The God Who Guards the Leaves

The lord of the Biwa mansion sent to Toshiko's house, where a kashiwa oak was growing, asking leave to have a branch broken off. She had a branch broken, wrote a poem, and sent it with the branch: "Waga yado o itsuka wa kimi ga narashiba no narashigao ni wa ori ni okosuru". The lord of Biwa's reply was "Kashiwagi ni hamori no kami no mashikeru o shirade zo orishi tatari nasaru na". That is the whole of the section.
The lord of the Biwa mansion is Fujiwara no Nakahira, so called from the residence where he lived. Toshiko was the wife of Fujiwara no Chikane and appears in the sixty-sixth and sixty-seventh sections. The kashiwa oak was held to house the god who guards the leaves.
The setting is Toshiko's house, where a kashiwa oak grew in the garden.
What prompted the poem was the messenger from the Biwa mansion asking leave to break off a branch. She had one broken and wrote this to go with it.
He answered with a poem of his own, and the exchange closes the section. This poem was later included in the Gosen-shū.

The opening asks when he became so familiar, in a tone that carries its own answer: he did not.
The word for the oak leaf in the third line supplies, by its sound, the phrase that follows. The same sound is struck twice in succession.
That phrase means the face of someone quite at home, a manner without ceremony, and it is what she objects to in the way he asked.
The closing names the sending for a branch. She gives him the branch and takes issue with the asking. Complying and adding a word about it is the same movement as the willow branch in the third section, where gift and poem work as one.
