How does the poet use symbolism in the poetry collection, A Visit to William Blake’s Inn?

In Poem 2, the boy makes the transition from his comfortable, predictable home to his room at the inn. The rabbit kindly helps him make that transition by promising him safety and security, replacing his familiar items with those that will be safe and appropriate for his stay in the inn. Even the bear, who will embrace the boy, becomes safe with the rabbit's explanations.
