Chapter 47 uses several metaphors to describe Sai's power and the abundance of his teachings. Can you explain some of them?

Chapter 47 is rich with metaphorical language to illustrate spiritual truths. It compares worldly existence to a firefly that hides, losing its luster before the "sun of His grace." Another powerful metaphor, described in Chapter 47, involves the River Ganges, which, despite purifying the world, seeks the dust from the feet of saints to cleanse its own accumulated impurities. The author also describes being on the "shore of the ocean of Sai's stories" and sitting under a "Kalpataru (wish-fulfilling tree)," signifying an endless supply of divine wisdom. He further asks, "In the house of the Sun, who worries about a lamp?" to emphasize the overwhelming abundance of grace and knowledge available to a devotee of Sai.
