Ima zo shiru omoi no hate wa yo no naka no ukigumo ni nomi majiru mono to wa - Kinyo Wakashu(English Translation & Meaning)

今ぞ知るおもひの果ては世の中の
うき雲にのみまじるものとは

Roma-ji: Ima zo shiru omoi no hate wa yo no naka no ukigumo ni nomi majiru mono to wa
English Translation: Now at last I know,
the end of the burning fire
of longing becomes
in this world of ours only
mingled with the drifting clouds
Meaning: Now I know it at last: the fire of longing ends only by mingling with the sorrowful drifting clouds of this world.
Commentary: Book Ten Miscellaneous Poems II 621

Now at last the poet knows that the fire of longing ends only by mingling with the drifting clouds of this world. Watching the smoke of a cremation rise into the sky and mingle with the clouds, the poet expresses the sorrow of coming to know how fleeting a human life is.
The next poem, 622, also sings of drifting clouds and the smoke of a cremation, and the two are placed side by side. The opening line ima zo shiru also echoes kyō zo shiru in the first line of 636 in this book.

First line, 'ima zo shiru', means now I know, the particle zo answered by the attributive shiru; the poem breaks after the first line and is inverted with what follows. It echoes kyō zo shiru in the first line of 636 in this book.
Second line, 'omoi no hate wa', means the end of the fire of longing, joining the hi of omoi with hi, fire, pointing to the funeral fire.
Third line, 'yo no naka no', means of this world.
Fourth line, 'ukigumo ni nomi', means only into the drifting clouds, joining ukigumo, floating clouds, with uki, sorrowful. The same ukigumo appears in the second line of the next poem, 622.
Final line, 'majiru mono to wa', means that it mingles, an inversion turning back to shiru in the first line.
