Robert Bly: Poets - Bees of the Invisible

Mallarme believed there should be mystery in poetry, and urged poets to get it, if necessary, by removing the links that tie the poem to its occasion in the real world … It was Rilke who created the metaphor that poets are 'bees of the invisible'. Making honey of the invisible suggests that the artist remains close to his own earthly history, but moves as well toward the spiritual and the invisible.
