Why does the text compare the purifying power of saints to the River Ganges, and what does this reveal about the stories in the Sai Satcharitra?

Chapter 47 of the Shri Sai Satcharitra uses a powerful analogy involving the River Ganges to illustrate the supreme purity of saints like Sai Baba. The text explains that while the Ganges washes away the sins of the world, she herself becomes soiled and desires the dust from the feet of saints to wash away her own accumulated impurities. As detailed in this chapter, this metaphor underscores that saints possess a purifying power greater than even the holy river. The narrative then introduces the story from Sai's mouth as supremely holy, capable of severing the bonds of Karma for anyone who listens, emphasizing its profound spiritual significance.
