Why did Madhavrao travel to Nagar, and what was the outcome of his visit to his father-in-law's house?

As detailed in Chapter 51, Madhavrao Deshpande's journey to Nagar was prompted by an urgent telegram from his father-in-law. The message stated that his mother-in-law was very ill and that he should come immediately. After getting Baba's permission, he took the train from Chitali and arrived in Nagar. However, upon visiting his father-in-law's house, Madhavrao discovered that his mother-in-law's health was actually fine. This 'false alarm' is portrayed as part of a larger divine plan to bring Madhavrao to Nagar precisely when Dixit needed help getting to Shirdi.
