Describe the scene involving Madhavrao and the request for Dakshina that occurred after the author finished his reading.

As soon as the author's story about the Bhagavat reading concludes, Chapter 18 narrates a subsequent event. Madhavrao arrived with a direct message from Sai Baba. He told the author that Baba had suddenly remembered him and sent Madhavrao to fetch fifteen rupees as Dakshina from 'Shama.' Baba also instructed Madhavrao to sit and talk with the author for a while. The author was extremely surprised by this monetary request. In response, he told Madhavrao to convey his 'namaskar' (a respectful greeting) as his form of Dakshina instead of rupees, to which Madhavrao agreed, noting that fifteen namaskars had been received.
