Tani sebami mine ni haitaru tamakazura taemu no kokoro waga mowanaku ni

谷狭み峰に延ひたる玉葛
絶えむの心我が思はなくに

Roma-ji: Tani sebami mine ni haitaru tamakazura taemu no kokoro waga mowanaku ni
English Translation: The valley's narrow,
so up to the peak it climbs,
the jeweled creeper:
never a heart to break it off
have I harbored, love, in me.
Meaning: Like the jeweled vine that climbs up to the peak because the valley is narrow, I hold no heart that would break our bond.
Commentary: Book Fourteen Azuma Poems 3507

Headnote continued from the preceding poem: "Sōmon (Love Exchanges)"
Like the vine that has crept all the way up to the peak because the valley is narrow, the singer has no heart to break off their bond. The vine that stretches on and on carries a love that will not end.
It is one of the love exchanges. Likening a vine to lasting love echoes 3434 from Kōzuke, "Asoyama tsuzura no o hiromi hainishi mono o aze ka taesemu."
The poet is unknown. The Azuma uta are thought to have been sung among the people of the eastern provinces, and they are marked by plain, open-hearted expression mixed with local dialect.

First line, "tani sebami": "Sebami," in the "o ... mi" pattern: because the valley is narrow.
Second line, "mine ni haitaru": "Creeping up to the peak."
Third line, "tamakazura": "Tama" is an honorific: a lovely vine. The first three lines form a preface.
Fourth line, "taemu no kokoro": "A heart that would break off," laid over the vine breaking.
Final line, "waga mowanaku ni": "Naku ni" is an exclamatory negative: I hold no such thought.
