The Soul

We all wondered about Oliver's use of the I,II,III,IV intermingled her poem about the Whale Bone. It came to me last night what it means to me ... I believe the soul has four parts: emotional, spiritual, intelletual, and physical. These are the areas where we grow and become who we are - in essence our soul. Perhaps, Oliver has her list of four parts and by putting the numbers into the poem, she found a way to honor the four sections of the soul???? Just a thought.
