The text says 'While humans make their plans, God has another plan.' How is this idea illustrated by the events leading to Dixit's trip to Shirdi?

This philosophical statement is perfectly illustrated by the events described in Chapter 51. The "human plan" was the logical discussion between the Mirikars about who should take Dixit to Shirdi. In contrast, "God's plan," as the narrative presents it, was a far more intricate and seemingly coincidental sequence of events. This divine plan involved a false telegram causing Madhavrao Deshpande to travel to Nagar at the exact right time, the chance spotting of Madhavrao by Panshe and Gadre, and their immediate realization that he was the ideal guide for Dixit. The way these disparate elements converged to resolve Dixit's overwhelming anxiety is portrayed not as a human arrangement, but as a compassionate and miraculous intervention by a higher power, demonstrating a plan beyond human comprehension.
