Answer
Brief Explanations:
In Song of Myself, Walt Whitman emphasizes the self - exploration and the expansive nature of the self. The travel images in part 46 are not about the impermanence of life in a negative sense (not just fleeting as in impermanence). Growth in the poem is more about the all - encompassing nature rather than just a steady forward movement. And the poem is about the self in a very broad, expansive way. The travel images suggest going beyond one's immediate self, extending, which is in line with the idea of expansiveness.
Answer:
They suggest expansiveness, or extending one's reach outward.
