How does Nelly Sachs use imagery in But Perhaps God Needs the Longing?

Simply put, imagery refers to the images suggested by a poem. The relationships between images can suggest important meanings in a poem. With imagery, the poem uses language and specific words to create meaning. For instance, Sachs uses imagery to demonstrate the cycle of life and death. The wreath is a circle without beginning and end. Birth and death are the cyclical representations of nature. Each birth must end in death, but the dead are not forgotten, according to Sachs, since they remain alive in memory.
