Can you explain the circumstances of Madhavrao Deshpande's unexpected arrival in Nagar and how he ended up helping Dixit?

Madhavrao Deshpande's arrival in Ahmednagar was a pivotal, yet unexpected, event. Chapter 51 recounts that while Dixit was worrying about his Shirdi trip, Madhavrao appeared in Nagar, to everyone's amazement. The reason for his journey was a telegram from his father-in-law, urgently summoning him due to his mother-in-law's supposed illness. After getting Sai Baba's permission, Madhavrao traveled by train to Nagar. Upon his arrival, he was coincidentally seen by Nanasahib Panshe and Appasahib Gadre, who knew he was the 'priest of Shirdi' and the ideal guide for Dixit. They sent him to the Mirikars' house to meet Dixit. Interestingly, Madhavrao later found his mother-in-law's health to be perfectly fine, highlighting the miraculous nature of his timely presence to aid a fellow devotee.
