Can you explain the metaphors used to describe Sai Baba and the nature of his stories in this chapter?

Chapter 47 employs rich metaphors to convey the infinite grace of Sai Baba and the spiritual nourishment his stories provide. He is compared to the "Kalpataru," a celestial wish-fulfilling tree, signifying that under his protection, any desire for stories is instantly granted. The text also likens him to the Sun, in whose presence a lamp is useless, highlighting his supreme spiritual effulgence. Having Sai as a "perpetual protector" ensures a constant supply of the "nectar of stories," which devotees can enjoy to their heart's content. These metaphors, found in verses 17, 18, and 19 of Chapter 47, illustrate that with Sai, there is an endless, accessible ocean of spiritual wisdom and joy.
