I think it's interesting that I chose the same poem as Christian... I agree that this poem undoubtedly captures the author's individual experience, embodiment, and then explanation of the month of October. Like the book says, this poem is an "individual, flickering moment of human feeling and consciousness and perception." It's the narrators heart revealed through their description of nature.
So I kind of understood indirection to be sort of metaphorical speak or a way of writing a poem in which emotions are understood but not explicitly stated. I chose this poem because it seems to be using phrases like "When the city is rotting" and "Feathered language / Heavy as freedom" to convey emotion without explicitly stating what that emotion is.
