Commentary: Book Sixteen Miscellaneous Poems II 1145

Headnote: "Feeling helpless in illness, I sent this to Taifu."
The poet says that the vow made for ten thousand ages will come to nothing and he will surely become a laughingstock. Disheartened by illness, he confides to Taifu his fear that their pledge of eternity may fail through his death.
According to the headnote, he sent it to Taifu saying that he felt helpless in his illness. Taifu's reply follows in the next poem, forming an exchange.
The poet, Fujiwara no Atsutoshi, was the eldest son of Fujiwara no Saneyori and died young.

The first line, "Yorozuyo o," means "for ten thousand ages," referring to their vow of an eternal bond. "Yorozuyo" also appears in the third line of the next poem.
The second line, "chigirishi koto no," means "what we pledged," with "shi" the attributive of the past "ki." The fourth line of the next poem takes up this line.
The third line, "itazura ni," means "in vain," referring to the vow's going unfulfilled.
The fourth line, "hitowarae ni mo," means "a laughingstock too."
The last line, "narinubeki kana," means "I will surely become," with "nubeshi" strong conjecture and "kana" exclamatory.
