Can you explain the various metaphors used in Chapter 47 to describe Sai Baba's greatness and the benefit of being his devotee?

Chapter 47 employs several rich metaphors to convey Sai Baba's divine stature. He is called the "crown jewel among saints," whose feet can purify a soul's impurities. For a devotee, being under his protection is compared to sitting under the shade of a "Kalpataru (wish-fulfilling tree)," where desires are fulfilled instantly, guaranteeing an endless supply of his story-nectar. The text also likens Sai to the Sun, in whose house a lamp is redundant, and portrays him as a perpetual protector who provides a constant stream of nectar, making a devotee immune to the poison of worldly troubles.
