In Chapter 47, there's a metaphor about a river wanting to be purified. What does this imagery represent?

The metaphor in Chapter 47 of a river desiring purification represents a soul burdened by worldly attachments and accumulated sins. The text describes the river wanting to "wash away her accumulated impurities" and yearning for the "dust from the feet of saints" to touch it, as it knows there is no other deliverance from its sins. This imagery symbolizes an individual's deep spiritual longing for cleansing and liberation from their negative karma. The "impurities" are the sins and attachments of worldly life, while the "river" is the soul seeking release. As Chapter 47 suggests, the "saints," epitomized by Sai Baba, are the source of grace, and contact with them is presented as the ultimate means to achieve spiritual purification and wash away one's karmic debts.
