After giving birth to twins, playwright Sarah Ruhl was diagnosed with Bell’s palsy, a paralysis of the seventh cranial nerve that severely limits facial expression, even—and especially—one’s ability to smile. Though most suffering from this condition get better within a year, for Ruhl, the road to recovery has been much slower. In her new memoir, "Smile: The Story of a Face," Ruhl reflects on her journey of reoccupying her body and reclaiming her capacity for joy. In today’s episode of Tricycle Talks, Tricycle editor-in-chief James Shaheen sits down with Ruhl to discuss Zen koans, the overlooked beauty of asymmetry and imperfection, and how Tibetan Buddhism brought her back to her Catholic roots.
