Chapter 47 uses the metaphor of the Bhagirathi (Ganges) River. Can you explain this metaphor and its significance regarding the status of saints like Sai Baba?

In Chapter 47, the Bhagirathi, or Ganges River, is depicted as a great purifier that washes the sins of the world but becomes soiled itself in the process. The metaphor illustrates that even a sacred entity like the Ganges needs its own purification. The chapter explains that the river desires the dust from the feet of saints, knowing this is the only way to achieve deliverance from the accumulated impurities. As presented in Chapter 47, this imagery elevates saints like Sai Baba to a status higher than even the most revered natural elements. It powerfully suggests that while the Ganges can wash away ritualistic impurities, only the grace of a true saint can purify the soul from the deep-seated bonds of Karma.
