Book excerpt: Three of Marianne Williamson's previous bestsellers -- A Return to Love, A Woman's Worth, and Illuminata -- explored the issue of relationships. Now, in this deeply personal collection of essays, prayers, and self-reflection, she turns to romantic love. In Illuminata, Williamson wrote that "we experience God to the extent to which we love, forgive, and focus on the good in others and ourselves." Now, in Enchanted Love, she writes that "enchanted partnership begins with the conscious understanding, on the part of two people, that the purpose of their relationship is not so much material as spiritual, and the internal skills demanded by it are prodigious." High romance, she says, "is not about past or future. It is not about practicality. It is not about society or worldly routines. It is an audacious ride to the center of what is, at the heart of every person. It is a bold and masterful inquiry into what two people really are and how we might become, while still on earth, the angels who reside within us."
