classic waka stream

雨降ればたぎつ山川岩に触れ
君が砕かむ心は持たじ
Roma-ji

Ame fureba tagitsu yamagawa iwa ni fure kimi ga kudakamu kokoro wa motaji

English Translation
When the rain comes down,
rushing mountain streams dash hard
striking on the rocks—
such a heart as breaks your own
I will never hold, my love.
Meaning
Like the mountain stream that rushes when the rain falls and dashes itself against the rocks—I will never have a heart that shatters yours.
Commentary
Book Ten Autumn Love Poems 2308

Headnote continued from the preceding poem: "Poems in Dialogue"
This poem answers that the speaker will never hold a heart that would shatter the beloved's, as a mountain stream swollen with rain dashes against rocks, and it is thought to form an exchange with the preceding poem. To the partner lamenting gossip, it vows sincerity, promising not to cause pain. The left note says this poem is not like an autumn poem, but it is included because it answers the preceding one.

The first line, "when rain falls," gives the condition.
In the second line, "tagitsu yamagawa," "tagitsu" means to seethe and rush.
The third line, "striking the rocks," with the upper lines forming a preface leading into "kudaku," to shatter.
The fourth line, "that would break your heart," names the kind of heart.
In the last line, "kokoro wa motaji," "ji" expresses negative intention: I will not have such a heart.
