Can you explain the metaphors used in this chapter to describe the abundance of Sai's grace and stories?

Chapter 47 employs several powerful metaphors to illustrate the endless nature of Sai Baba's grace and the stories that flow from it. The narrator compares the experience to sitting on the shore of the vast "ocean of Sai's stories," suggesting an inexhaustible supply (47.17). Sai himself is likened to the mythical Kalpataru, or wish-fulfilling tree, under whose shade desires are instantly fulfilled. Further metaphors in verse 18 contrast Sai's presence with worldly needs: being in his care is like being in the "house of the Sun," where a small lamp is unnecessary. Similarly, for one who constantly drinks the nectar of his grace, a wave of poison has no effect. These images collectively portray Sai as a perpetual protector who provides boundless spiritual nourishment.
