What is the theme in A Visit to William Blake's Inn by Nancy Willard?

The spiritual or mythical world being around us is a theme of thse poems. At the end of this book of poems, it is clear that the characters can only stay in Blake's inn for a short time, actually the undetermined time it takes to experience the poems herein. In this short visit, the reader might wonder why certain stories, experiences and thoughts were chosen. Part of the nature of the spiritual world rendered by Nancy Willard is the immediacy of that world. Whatever is going on in the moment is what is important, and the mystical or spiritual nature of the experience is what matters.
