Kimi wa kimi ware wa ware tomo hedatereba kokorogokoro ni aran mono ka wa - Izumi Shikibu Nikki(English Translation & Meaning)

君は君我は我ともへたてれは
こゝろこゝろにあらん物かは

Roma-ji: Kimi wa kimi ware wa ware tomo hedatereba kokorogokoro ni aran mono ka wa
English Translation: "You are you, I am I"—
though we set ourselves apart
as two in this way,
could our hearts ever really be
divided, each its own?
Meaning: Even if we draw a line between us, saying you are you and I am I, how could our hearts ever truly be two separate hearts?
Commentary: 38 Of One Heart

The day after their exchange about the sadness of evening, early in the morning, the frost lay very white. A letter came from the prince: "Well, how are you at this hour this morning?"
The woman is Izumi Shikibu, daughter of Ōe no Masamune and, as the wife of Tachibana no Michisada, Governor of Izumi, mother of Koshikibu no Naishi. The Prince of the Dazaifu is Prince Atsumichi, fourth son of Emperor Reizei, so called because he served as Governor-General of the Dazaifu.
When the prince's "Ware hitori omou wa omou kai mo nashi onaji kokoro ni kimi mo aranan" arrived with tender words, Izumi Shikibu sent back this poem.
Around this time, perhaps from a cold, she fell ill, though not seriously, and the prince wrote often to ask after her.

The opening lines mean "you are you and I am I," doubling both "you" and "I" and setting them side by side to sharpen the idea of two separate beings. The third line means "even if we keep apart."
The lower verses ask "could our hearts really be separate?" where "kokorogokoro" means hearts each apart from the other, with a rhetorical ending. Taking up his "the same heart," she answers that their hearts are one without his needing to ask, and so dispels his unease.
