What metaphors does the author use in Chapter 3 to describe Sai Baba's grace and the author's own role in writing the Satcharitra?

In Chapter 3, the author employs beautiful metaphors to convey the nature of Sainath's grace and his humble position as a narrator. He states that he is merely a pretext and that Sai Himself is doing the work. This is illustrated with the analogy of a 'motherly cow' that naturally feels a surge of milk and does not withhold it from her calf, symbolizing Sai's inherent and overflowing love. The chapter also compares Sai to a 'cloud of joy (mother)' that rains down to fulfill the spiritual thirst of the devotee, who is likened to a hopeful 'Chataka bird,' thus intensely satisfying the devotee's soul.
