Describe the sequence of fortunate coincidences that assisted Kakasaheb Dixit on his journey to Shirdi.

Chapter 51 recounts several strange and fortunate coincidences that facilitated Kakasaheb Dixit's journey. First, Nanasaheb Panshe and Appasahib Gadre providentially met Madhavrao, the perfect person to accompany Dixit. Second, a repaired portrait of Baba, which had come from Shirdi, happened to be at Mirikar's house at the exact moment Dixit was there. Third, when their train was found to be full, the train guard suddenly appeared and turned out to be an acquaintance of Dixit, arranging first-class seats for them. Finally, upon arriving at Kopergaon, they unexpectedly met Nana Saheb Chandorkar, who was also on his way for Baba's darshan.
