It seems like a huge coincidence that Madhavrao showed up in Nagar right when Dixit needed him. What was the story behind his sudden trip?

Madhavrao Deshpande's sudden arrival in Ahmednagar is portrayed as a divine intervention prompted by Dixit's strong desire. According to Chapter 51, Madhavrao received a telegram from his father-in-law in Nagar claiming that his mother-in-law was very ill and that he should come at once. Upon receiving Baba's permission, Madhavrao immediately took his family and caught a train to Nagar. The interesting twist is that when he later visited his father-in-law's house, he discovered his mother-in-law's health was perfectly fine. This false alarm served as the pretext to bring him to the exact place at the exact time he was needed by Dixit.
