I do not cross it in dreams.

Commentary
Book Eighteen Miscellaneous Poems II 980

Headnote: "Sent to someone who was in Koshi"
Sent to someone in the province of Koshi, this poem says that although the poet has never seen Shirayama there, every night in dreams he crosses that mountain to visit, conveying deep feeling for someone far away.
Following the previous poem, 979, it also sings of Shirayama in Koshi, so two poems on the mountain stand together. It echoes the sound of Shirayama in shiranedomo, "though I do not know," and of Koshi in koenu, "not cross."
The author, "Ki no Tsurayuki" as written in kana, is Ki no Tsurayuki, the leading compiler of the Kokin Wakashū and author of its kana preface. He is also known as the author of the Tosa Diary and is one of the Thirty-Six Poetic Immortals.

The first line, "where my thoughts go out to you," means thinking of someone far away.
The second line, "Shirayama of Koshi," is the same mountain as in the previous poem.
The third line, "I have never known," echoes the shira of Shirayama in shira-nedomo.
The fourth line, "a single night," is paired with "in dreams."
The last line, "I do not cross it in dreams," uses a double negative to stress that he crosses every night. Koe, "cross," echoes Koshi in the second line, and zo governs the attributive naki.
