Harugoto ni kokoro o sora ni nasu mono wa kumoi ni miyuru sakura narikeri - Shika Wakashu(English Translation & Meaning)

春ごとに心をそらになすものは
雲居に見ゆる桜なりけり

Roma-ji: Harugoto ni kokoro o sora ni nasu mono wa kumoi ni miyuru sakura narikeri
English Translation: Each and every spring
what sets my heart adrift
in the empty sky
is the cherry that appears
high among the clouds.
Meaning: What sets my heart wandering in the sky each spring, I see now, is the cherry blooming high among the clouds.
Commentary: Book One Spring Poems 25

The poet realizes that what unsettles his heart every spring is the cherry seen high in the sky. The wit lies in linking a heart gone up into the air with cherries seen in the sky.
The author is said to be Kaishū. Sharing its last line with the preceding poem, it is the second of two poems that end by recognizing the cherry.

The first line, "each and every spring," means whenever spring comes; the same phrase opens 32.
In the second line, "sora" is a pivot word meaning both absent-minded and the sky.
The third line, "what sets," means the thing that makes it so, the answer being held for the last line.
The fourth line, "high among the clouds," means seen high in the sky, an associated word with the "sora" of the second line; it also suggests the court, connecting with the "ninefold palace" of the preceding poem.
The last line, "is the cherry," repeats the preceding poem's last line and closes with "keri" of realization.
