What are some of the key analogies used in Chapter 47 to describe the greatness of Sai Baba and his stories?

Chapter 47 employs several powerful analogies to illustrate the supreme nature of Sai Baba and his teachings. It compares Sai's grace to the sun, in whose light the 'firefly of worldly existence' loses its luster. The chapter also uses the metaphor of the River Ganges, which becomes soiled by washing the world's sins and desires the dust from a saint's feet for its own purification. Furthermore, being in Sai's presence is likened to being under the shade of a Kalpataru (wish-fulfilling tree) or 'in the house of the Sun,' where a lamp is not needed, signifying that all needs for stories and spiritual nourishment are effortlessly met.
