She likens the metamorphosis that she is experiencing to the metamorphosis that occurs when a caterpillar becomes a butterfly. She recognizes that she is still evolving and changing, both physically and emotionally, and that the changes happening within her are as inevitable as the coming of spring.
Although the speaker can see that she is changing into a new form, she assures the world that the core of her being remains unchanged. Despite her physical transformations, her emotions and beliefs are unyielding. She is still the same person on the inside, even if her exterior appears different.
The speaker ends the poem by musing on the concept of death. She considers how her body will eventually decay and return to the earth, but she finds solace in the fact that her spirit will live on. Her essence, she believes, will transcend the confines of her physical body and find eternal life.
Overall, "Metamorphosis" is a moving and introspective poem that delves into the complexities of human existence and change. Hansen reflects on the inevitable process of aging and the concept of personal growth, ultimately highlighting the power of the spirit and the enduring nature of the human soul.
