Describe the plea made by the parents to Sai Baba upon their arrival in Shirdi, as narrated in Chapter 34.

The narration in Chapter 34 vividly portrays the parents' desperate plea to Sai Baba. Upon gaining his darshan, they immediately prostrated at his feet. With choked voices, folded hands, and "pitiful faces," they explained their son's unbearable suffering. They expressed their own exhaustion and helplessness, confessing, "we do not know what to do next; we see no way out for us." They directly appealed to Sai Samarth, explaining that they had come a long way after hearing of his greatness and were now seeking refuge with total devotion. Their specific request was for Sai to "place your hand of protection on his head and remove this ailment," effectively begging him to grant their son the gift of life.
