What metaphors are used in Sister Outsider: Essays and Speeches by Audre Lorde?

The female becomes a metaphor for power. Audre Lorde formulates the idea of an emotional source of power in several of the essays in Sister Outsider. This emotional "place" is an ancient, hidden reserve of creativity which Lorde describes as "non-European," meaning that it is not recognized by the white-dominated society in which she was brought up. The power found here is a feminine, creative power and can be expressed most easily through poetry.
