Why does the author pause the main story of Sai's life to tell the story of how he was named 'Hemadpant'?

The author pauses the main narrative to explain the origin of his name, 'Hemadpant,' for a few key reasons. As explained in Chapter 2, he is fulfilling a promise made to the listeners in the previous chapter. The idea was triggered by contemplating Baba's words, "Do not engage in dualistic explanations." He acknowledges that readers would naturally be curious about the name 'Hemadpant' appearing at the end of each chapter. He feels that telling this sub-story is an inspiration from Sai and will satisfy the listeners' curiosity before he continues with the sequence of Sai’s life story.
