When all other remedies fail, what does the story in Chapter 34 suggest one should do?

The story of the doctor's nephew in Chapter 34 serves as a powerful illustration of turning to Sai Baba when all other options are exhausted. The family first tried numerous medical treatments from expert physicians and surgeons, both native and foreign, and even resorted to worshipping other deities, but nothing worked. It was only when they reached their absolute limit and felt helpless that they heard of and decided to seek refuge with Sai Baba. The chapter shows that this final resort to the Sadguru was the correct path. Sai Baba reassured them, saying, "Those who seek shelter in the Masjid shall never face downfall, even at the end of an era." This suggests that seeking refuge with Sai with total devotion is the ultimate solution when all other paths are closed.
