What was the initial reason for Madhavrao Deshpande's trip to Nagar, and what did he find out when he got there?

Madhavrao Deshpande's journey to Nagar was prompted by an urgent telegram from his father-in-law. Chapter 51 states that the telegram claimed his mother-in-law was very ill and that he should come immediately with his family. Acting on this, Madhavrao obtained Baba's permission and traveled to Nagar. However, upon visiting his father-in-law's house, he discovered that his mother-in-law’s health was actually fine. This surprising turn of events is presented in the narrative as part of a larger, unseen plan to bring Madhavrao to the city at the exact moment he was needed by another devotee, Kakasaheb Dixit.
