Based on the stories of Kaka Mahajani and Dattopant, what is the nature of a saint's healing power?

Chapter 13 illustrates that a saint's healing power transcends conventional medicine. For Kaka Mahajani, suffering from severe diarrhea, the cure was not a typical remedy but roasted peanuts and water given by Baba during a fit of rage, followed by the simple declaration that his illness had stopped. Similarly, Dattopant of Harda, who suffered a stomach ache for fourteen years, was healed by Baba's hand on his head and the gift of Vibhuti. The text explicitly states, 'the saint's word is the medicine,' and for those who accept what they give as prasad, 'no other medicine is needed.' This suggests that the true healing comes from the saint's grace, intention, and blessings, which can manifest in seemingly strange or simple ways.
