The poet contemplates (metaphorically) an abandoned, overgrown garden. "What god is proud / of this garden / of dead flowers, this underwater / grotto of humanity?" he asks. He sees limbs waving, faces drooping, and voices clawing. He recognizes great medical figures like Charcot and Alzheimer. There are no gardeners. As he turns away, he tries to take solace in the thought that somewhere "there is another / garden, all dew and fragrance." [30 lines]
I have this that I must do / One day." I must take the last step, go down into the "green darkness," and find the "door to myself." There is no map, no assurance, and no way of avoiding the final plunge into darkness.
