How does Chapter 47 explain the purifying power of saints and their stories?

Chapter 47 uses a powerful metaphor to explain the purifying power of saints and their narratives. It describes the River Ganges (Bhagirathi), which purifies the world but becomes soiled in the process. To wash away her own accumulated impurities, she "desires the dust from the feet of saints," knowing there is no other deliverance from her sins. As this analogy in Chapter 47 illustrates, saints possess a supreme purifying quality. The chapter then extends this power to the story itself, calling it "supremely holy" and stating that upon hearing it, "the bonds of Karma will be severed." This suggests that the narratives of great saints like Sai carry the same cleansing power as their physical presence.
