In what way does the author of the Satcharitra describe Sai Baba's role in the creation of the book in Chapter 3?

In Chapter 3, the author humbly describes his role as merely a pretext, asserting that Sainath Himself is the true force behind the work. The author uses beautiful analogies to explain this concept. He compares Sai's grace to a motherly cow who naturally feels a surge of milk for her calf, illustrating the unconditional and innate nature of Sai's love. As this chapter further explains, the author sees himself as a 'Chataka bird' whose small thirst is being quenched by the 'cloud of joy,' which is Sai, who rains down His grace to 'satisfy the devotee intensely.'
