Describe the reasons the author provides for pausing the main narrative to tell the story of how he was named 'Hemadpant'.

The author explains his decision to insert this sub-story for two main reasons. First, as mentioned in Chapter 2, he is fulfilling a promise made to the listeners at the end of the first chapter. Second, he addresses a natural curiosity that he anticipates from his readers. Since the phrase "Composed by the devotee Hemadpant" appears at the end of every chapter, he believes a doubt would naturally arise about who this person is. To satisfy that curiosity, which he feels is also an inspiration from Sai, he respectfully shares the short story of his naming ceremony before continuing with the main life story of Sai Baba.
