Mi wa sutetsu kokoro o dani mo haburasaji tsui ni wa ikaga naru to shirubeku

away; at least my heart
I'll not cast adrift,
so that I may come to know
how all of it will end
Meaning
I have already cast away my body; at least I will not let my heart go astray, so that I may see how it all turns out in the end.
Commentary
Book Nineteen Miscellaneous Forms 1064

Headnote: "Topic unknown"
Having abandoned his body, the poet resolves at least to keep hold of his heart so that he can witness his own end. The quasi-logical separation of body and heart is what marks the poem as haikai.
The author, "Okikaze," is Fujiwara no Okikaze. The son of Fujiwara no Michinari, he held provincial posts in Sagami and Shimōsa. Also skilled at the koto, he is one of the Thirty-Six Immortal Poets.

First line, "Mi wa sutetsu," uses perfective "tsu": my body I have already cast away. The poem breaks after the first line.
Second line, "kokoro o dani mo," uses "dani," at least: my heart, at the very least.
Third line, "haburasaji," uses "haburasu," to cast adrift, with negative intent "ji."
Fourth line, "tsui ni wa ikaga," means in the end, how.
Fifth line, "naru to shirubeku," means so that I may know what becomes of me, inverted to follow the third line.
