今日もなほ惜しみやせまし法のため
散らす花ぞと思ひなさずは

Roma-ji: Kyō mo nao oshimi ya semashi nori no tame chirasu hana zo to omoinasazu wa
English Translation: Today once again
would I have grieved for them so,
if not for the Law
these are blossoms that we scatter,
had I not made myself think
Meaning: Today again I would have grieved over the falling blossoms, had I not told myself that these are flowers scattered for the sake of the Law.
Commentary: Book Ten Miscellaneous Poems II 643

Had the poet not resolved to see these as blossoms scattered for the sake of the Law, he would have grieved over their falling today as always. Drawing on the scattering of flowers as an offering to the Buddha at a Buddhist service, the poem says that the falling of blossoms one usually mourns brings no regret when seen as done for the Law.
Near the opening of this book, 606 lamented that the poet would scatter before the flowers, while this poem sees the falling blossoms as an offering for the Law, singing of the same scattering of flowers with a different heart.

First line, 'kyō mo nao', means today again.
Second line, 'oshimi ya semashi', means would I have grieved, the particle ya answered by the attributive of the counterfactual mashi; the poem breaks after the second line.
Third line, 'nori no tame', means for the sake of the Law.
Fourth line, 'chirasu hana zo to', means that these are flowers we scatter, pointing to the offering of scattered flowers. Like chirinubeki kana in 606 in this book, it sings of falling blossoms.
Final line, 'omoinasazu wa', means had I not made myself think, the continuative of the negative zu with wa expressing a supposition. It is inverted with the second line.
