Onoga mi no onoga kokoro ni kanawanu o omowaba mono wa omoishirinamu - Shika Wakashu(English Translation & Meaning)

おのが身のおのが心にかなはぬを
思はばものは思ひ知りなむ

Roma-ji: Onoga mi no onoga kokoro ni kanawanu o omowaba mono wa omoishirinamu
English Translation: If one but considers
that one's own self will not
bend to one's own heart,
then surely one will come to
understand the way of things
Meaning: If you consider that your own self does not obey your own heart, you will surely come to understand how things are.
Commentary: Book Nine Miscellaneous Poems I 310

If one considers that even one's own self does not bend to one's own will, the poet says, one will understand that others' hearts cannot be bent either. Repeating "onoga" (one's own) turns the eye inward, teaching self-reflection before resenting others.
Like poem 279 of this book, which sings of the futility of resenting others without knowing one's place, it looks closely at the relation between self and heart.

The first line, "onoga mi no" (one's own self), repeats "onoga" with the second line.
The second line, "onoga kokoro ni" (to one's own heart), names what the self fails to obey.
The third line, "kanawanu o," uses the attributive negative and "o": that it does not accord.
The fourth line, "omowaba mono wa," is a hypothetical with the irrealis and "ba": if one thinks of this.
The final line, "omoishirinamu," combines the intensive "nu" and conjectural "mu": surely one will understand.
