Former Catholic nun, world-renowned religious scholar and author, Karen Armstrong discusses her memoir, "The Spiral Staircase." Karen discusses the details of her fascinating spiritual journey, which began when she joined a convent at the age of 17. Hoping to forge a deep connection to God, her inspiration was met with harsh disillusionment. Karen says she was deeply unhappy as a nun and unable to pray. Seven years later, she left the convent feeling like a failure, with her future in question. Karen says she avoided all organized religion for more than a decade, but then returned to the subject years later as a writer and scholar after experiencing an "awakening" while on assignment in Jerusalem. In our “perilously divided world,” we need to live more compassionately now more than ever, she says. In her book "Twelve Steps to a Compassionate Life," Karen outlines simple practices anyone can do in hopes of making a lifelong commitment to creating a more harmonious world. (Part 2 of 2)
