I really love your poem. "i broke heaven's bones" is a wonderful line -- The breaking bones is violent and visceral and really sets off against the expectations of heaven being serene and ephemeral. That same violent/visceral feeling rides into the second line with images of splintering, and the act of eating. The lines link further with ‘bones’ and ‘remains.’ It’s very strong!
With such a total rejection and conquest of heaven, the speaker’s invitation to be witnessed while transcending feels odd to me. But, obviously such reversals fit the haiku form, so it may not be a worthy complaint.
Closing ‘transcend’ with a comma is a subtle but significant indication that transcendence is not the end. I missed it on my first read, and really enjoyed noticing it on the second go-round.
This is great work. Reading it made my day.
