How did Madhavrao Deshpande become involved in assisting Kakasaheb Dixit's travel to Shirdi?

Madhavrao Deshpande's involvement was the result of what appeared to be a divine plan. According to Chapter 51, Madhavrao, a resident of Shirdi, received a telegram from his father-in-law in Nagar, urging him to come immediately because his mother-in-law was very ill. After getting Baba's permission, he traveled to Nagar. Upon his arrival, he was coincidentally met by Nanasahib Panshe and Appasahib Gadre, who directed him to Mirikar's house to meet Dixit Kaka, an 'extraordinary friend' who was desperate to go to Shirdi. When Madhavrao visited his in-laws, he found his mother-in-law's health was perfectly fine, suggesting the urgent summons was a pretext orchestrated by Sai to bring him to Dixit.
