In early April 2011, Floribeth Mora Díaz — then fifty years old, living at Dulce Nombre de Tres Ríos in Costa Rica — began suffering severe headaches. On April 8, angiography at the Hospital Calderón Guardia in San José disclosed a fusiform aneurysm of the right internal carotid artery. The neurosurgeon Alejandro Vargas Román pronounced it inoperable and gave her a month to live.
On May 1, 2011, Mora watched the beatification of John Paul II on television at her home. A photograph of the beatus's coffin was set beside her hospital bed. That afternoon, she reported hearing a voice — which she later identified as the pope's — say to her in Spanish: 'Levántate, no tengas miedo' ('Get up, do not be afraid'). She rose from the bed without pain and returned to normal life over the following weeks.
Follow-up scans on May 5, 2011 and again in November 2012 showed the aneurysm was gone. The medical committee of the Congregation for the Causes of Saints, chaired by Prof. Patrizio Polisca, met on April 27, 2013 and unanimously agreed that the cure had no natural explanation. On July 5, 2013 Pope Francis approved the cure as the miracle required for canonization; John Paul II was canonized on April 27, 2014. Floribeth Mora Díaz was present at the ceremony and remains in good health.
