Explain the incident where Sai Baba used a request for Dakshina to teach the author a lesson about discipline.

As detailed in Chapter 18, Sai Baba, knowing the author's inner turmoil, used a clever pretext to impart a lesson. He told the author to get up, go to Shama, and bring back fifteen rupees in Dakshina. This was not a genuine need for money but a compassionate act by Sainath to move the author from his state of jealousy. By obeying this order, the author went to Shama's house. There, he found a copy of the Nath Bhagawat which, by chance, opened to the exact portion he had lazily neglected to read that morning. This made him realize Baba had orchestrated the event to enforce the discipline of regular reading.
