What metaphors are used in But Perhaps God Needs the Longing by Nelly Sachs?

A metaphor is an analogy that identifies one object with another and ascribes to one object the qualities of a second object. The metaphor may be simple, as with a single comparison, or the metaphor may be much more complex, as in Sachs's case, where most of the poem functions as a metaphor. Sachs uses the stars as a metaphor for lost lives suggesting that each star is formed from the grief felt at a death. The stars metaphor allows Sachs to make grief a visible entity that everyone can see and acknowledge.
