Can you elaborate on the metaphors used in Chapter 47, such as the Ganges River and the Kalpataru, to describe the greatness of saints and their stories?

Chapter 47 uses powerful metaphors to convey spiritual truths. The River Ganges (Bhagirathi), known for washing away the world's sins, is depicted as becoming soiled herself and desiring the dust from the feet of saints for her own purification. This metaphor powerfully illustrates that the purifying power of a true saint like Sai Baba is supreme, even greater than that of the holy river. Later, as the author discusses the abundance of Sai's stories, he uses the metaphor of the Kalpataru, the celestial wish-fulfilling tree. He writes in Chapter 47 that being a devotee of Sai is like sitting under the shade of the Kalpataru, where the desire for stories is fulfilled the moment it arises. This signifies the endless, readily available grace and wisdom flowing from Sai, making spiritual struggle unnecessary.
