The urgent voice in this poem tells the patient to "Be still." The patient is about to undergo a brain scan (CT or MRI?) and the poem consists of a series of instructions. Don't worry about the discomfort or the side effects of the dye, the poem demands, "forget that your cradled head / may reveal a hard secret soon," the only thing that matters is "the subtle / shading of mass, some new darkness afloat / in the brindled brain sea."
