ふりぬとていたくなわびそ春雨の
ただにやむべきものならなくに
Roma-ji

Furinu tote itaku na wabi so harusame no tada ni yamu beki mono nara naku ni

English Translation
Just because you've aged,
do not grieve so bitterly;
like the rain of spring,
you are not one who is bound
simply to cease and be done
Meaning
Do not grieve so deeply just because you have grown old; like the spring rain, you are not something meant simply to stop and be done.
Commentary
Book Two Spring Poems II 80

Headnote: "In reply to Mibu no Tadamine, who, while serving as a guard officer of the Left Inner Palace Guards, sent a letter in which he lamented his lot."
To Mibu no Tadamine, who lamented his lot, Tsurayuki replies that he need not grieve so for having grown old, for just as spring rain does not simply stop once fallen, he is not one whose course is ended. Overlaying the "falling" of spring rain with "growing old," the poet looks hopefully to his friend's future.
According to the headnote, Mibu no Tadamine, when he was a guard officer in the Left Inner Palace Guards, sent a letter in which he lamented his own situation, and this was the reply. Tadamine was a poet who served alongside Tsurayuki as a compiler of the Kokin Wakashū.
The poet, Ki no Tsurayuki, was a son of Ki no Mochiyuki. He was the leading compiler of the Kokin Wakashū and wrote its kana preface. He served as governor of Tosa, is known as the author of the Tosa Diary, and is counted among the Thirty-Six Immortal Poets.

In the first line, "furi" is a pivot word joining "growing old" and rain "falling." Whereas the book's opening poem, 47, laments old age, this closing poem encourages one who has grown old, so that the book begins with a lament over aging and closes with consolation for it. 74 of this book also sings of spring rain with the same pivot word.
In the second line, "na ... so" is a prohibition: "do not grieve so bitterly." The poem pauses here.
The third line, "harusame no," takes up "furi" from the first line and presents spring rain as a figure for Tadamine's situation.
In the fourth line, "tada ni" means "simply, to no purpose": "something bound simply to stop."
In the last line, "naku ni" gives a reason: "since it is not such a thing." It carries the encouragement that Tadamine is not one whose course ends here.
