Based on the provided stories, what is the significance of a saint's 'prasad' or blessing in overcoming physical suffering?

Chapter 13 provides powerful testaments to the belief that a saint's offering transcends conventional medicine. The text explicitly poses the question regarding Kaka's diarrhea, "What is the medicine for diarrhea? But the saint's word is the medicine." Kaka was cured by eating roasted peanuts given as prasad by Baba. In a similar vein, Dattopant, who suffered for 14 years, was cured not by a physical remedy but by Baba's hand on his head and the gift of Vibhuti. He himself believed only "a saint's look of love, a saint's prasad, and words of blessing" could help. These accounts from Chapter 13 emphasize that for a devotee with faith, the grace and blessing embodied in a saint's prasad are the ultimate cure for afflictions.
