How does Dillard feel about "shadows?" What does she write to show those feelings?

Dillard writes of shadow as a place of mystery. For Dillard, shadows represent that which is hidden. Dillard is on a quest to see into the shadow and understand what is hidden. Hers is both a quest grounded in the physical world and that of spirit. Besides knowing what lies in the physical world of shadows, Dillard also wants to see and understand that which is hidden in the spirit world, as a means of accepting, with grace, her own inevitable death.
