What is the purpose of the River Ganges analogy mentioned in Chapter 47?

The analogy of the River Bhagirathi (Ganges) in Chapter 47 serves to elevate the purifying power of saints above all else. The text explains that while the Ganges purifies the world by washing people's feet, she herself becomes soiled by the sins she absorbs. To cleanse herself of these accumulated impurities, the river longs for the touch of a saint's feet. As Chapter 47 poetically describes, the Ganges wonders, "When will the feet of saints touch me?" This metaphor powerfully illustrates that the holiness of saints like Sai Baba, who is called the "crown jewel among such saints," is so immense that even a sacred river like the Ganges seeks their presence for its own deliverance.
