When author and journalist Sally Quinn needs a moment of peace or clarity, she said, "I walk the labyrinth." A labyrinth walk has long represented a journey or pilgrimage and Quinn uses it for walking meditation -- her late husband, legendary Washington Post executive editor Ben Bradlee, even built one for her at their Maryland estate. Quinn, who launched the Post's 'On Faith' website as a self-proclaimed atheist, talks about her new memoir, "Finding Magic," her notorious D.C. dinner parties and discovering meaning in her life through the years she spent caring for Bradlee as he suffered with dementia, their son, who had heart defect and severe learning disabilities, and her ailing parents.
