Itsu o itsu to omoitayumite kagerō no kagerō hodo no yo o sugusuramu - Kinyo Wakashu(English Translation & Meaning)

いつをいつと思ひたゆみてかげろふの
かげろふほどの世を過ぐすらむ

Roma-ji: Itsu o itsu to omoitayumite kagerō no kagerō hodo no yo o sugusuramu
English Translation: When, I wonder, when,
thinking so I let my heart
slacken, like the haze
flickering for a moment,
do I pass this fleeting world
Meaning: Telling myself "someday, someday," I grow careless and let this world slip by, a world as brief as the flicker of a mayfly or a heat haze.
Commentary: Book Ten Miscellaneous Poems II 641

Thinking that someday they will devote themselves to the path, people grow careless and idly pass a world as short and fleeting as the brief flicker of a heat haze. The poem admonishes the heart that, though it knows how fleeting human life is, keeps putting off its devotion to the Buddhist path.
The opening line tayumi naku of 646 in this book stands in contrast to omoitayumite in the second line of this poem.

First line, 'itsu o itsu to', means when shall be the time, an extra syllable in the line. It expresses the heart that keeps saying someday.
Second line, 'omoitayumite', means thinking so and growing slack. It contrasts with tayumi naku in the first line of 646 in this book.
Third line, 'kagerō no', means of the heat haze, leading to the same sound kagerō in the fourth line.
Fourth line, 'kagerō hodo no', means as brief as a flicker, repeating kagerō from the third line to express a short and fleeting time.
Final line, 'yo o sugusuramu', means do I pass the world, closing with the present conjectural ramu.
