the sky and the rock

you do not have to look 
at the moon 
to know she is full.

she is my sister, 
full 
more than full 
more than infinite 
more than 
the line between the rock and the sky

she is my sister 
so i do not need to look 
to know her feelings are 
unknown

she is the moon 
so i do not need to know 
the properties of her fullness

tonight 
tomorrow too 
she will feel 
and she will be full

as full as the sky and the rock
as unknown as the line between
