What is the overarching message about faith and healing presented in the story of the bone-cyst in Chapter 34?

The story in Chapter 34 conveys a powerful message about the interplay between faith, surrender, and divine healing. It demonstrates that when all human efforts and medical science reach their limit, turning to a Sadguru with complete faith can provide a solution. The family of the sick boy only sought out Sai Baba after exhausting every other option. Their visit to Shirdi was an act of desperation and a final resort. Sai Baba's compassionate response, providing Udi and the assurance of protection for those who take refuge in him, underscores the theme that surrender and faith are paramount. The Udi is not just a medicine but a physical medium for the Guru's grace, effective against calamities where all else has failed.
