And I Am the arrow,
The dew that flies Suicidal, at one with the drive Into the red
Eye, the cauldron of morning. (23-28)
In this final, transformative moment, the speaker embraces the fact that she's now "at one" with the crazy, galloping drive of her horse. She's submitted to the experience of the wild ride. She's a free and unencumbered woman, and she's transformed (metaphorically) into an arrow. There's a lot of deathly imagery in these final lines, but death here seems like freedom, like a new start.
