What metaphors and previous stories does Chapter 47 use to emphasize the power and purity of Sai Baba's teachings?

Chapter 47 employs several powerful metaphors and references to highlight the significance of Sai's wisdom. It opens with the imagery of the River Bhagirathi (Ganges), which, despite purifying the world, desires the dust from a saint's feet to cleanse its own accumulated impurities. This illustrates the supreme purifying power of saints like Sai. The chapter also explicitly connects to the previous narrative, reminding listeners of the "story of the goats" to explain Baba's love for them stemmed from past-life memories. As detailed in Chapter 47, this serves as a narrative bridge to the main story about the downfall caused by greed, framing all of Sai's stories as an abundant, wish-fulfilling source of spiritual nectar.
