There is something urgent and present about metaphor. It opens up associations, references, notions, and at times all out lies to capture the subtle truths of our experiences. Metaphors allow writers to reach far beyond descriptive etchings to develop relationships with imagination and experiences, to color details complex or accessible, rich or muted, to give experience a new name.
Metaphors have a way of holding the most truth in the least space. –Orson Scott Card
