How does Chapter 3 use metaphors to describe Sai's grace and the nature of sharing His stories?

Chapter 3 beautifully employs metaphors to illustrate the nature of Sainath's grace in the telling of his stories. The narrator explains that Sai Himself is the true author, using the writer as a mere pretext. This divine inspiration is compared to a 'motherly cow' that feels a surge of milk for her calf and cannot withhold it, highlighting the natural, unconditional love of Sai. Another powerful metaphor used in Chapter 3 is that of a 'cloud of joy' raining down to satisfy the thirst of a 'Chataka bird.' This signifies that Sai, like a rain cloud, generously showers his grace to fulfill the spiritual thirst of his devotees, satisfying them intensely.
