How does Chapter 47 begin, and what does it teach about the spiritual importance of saints?

Chapter 47 opens with a powerful allegory about a river that feels impure and longs for purification. The river believes her "accumulated impurities" can only be washed away by the "dust from the feet of saints." She yearns for the day when saints will come to bathe in her, as she knows there is no other deliverance from her sins. As described in Chapter 47, this imagery establishes the central importance of saints as agents of purification and salvation. The narrative then immediately presents Sai Baba as the "crown jewel among such saints," whose speech forms the "purifying story" that follows, directly linking him to this profound spiritual power.
