Why does the book interrupt Sai Baba's life story to explain the origin of the name 'Hemadpant'? It seems like a useless, dualistic explanation, which the text itself warns against.

The author acknowledges this apparent contradiction and addresses it directly. In Chapter 2, after relaying Sai Baba's advice to 'not engage in dualistic explanations,' the author states that these very words reminded him of a promise made to the listeners. He recognized that the name 'Hemadpant' appearing at the end of every chapter would naturally create curiosity. He justifies this 'sub-story within the story' by stating that satisfying this curiosity is also a form of 'Sai’s inspiration' and promises that the main sequence of Sai's life story will continue immediately after, framing the digression as a necessary and inspired clarification for the reader.
