What series of 'strange coincidences' facilitated the journey of Sai's devotees to Shirdi as detailed in the provided text?

The journey to Shirdi was marked by a series of events that were perceived as more than mere coincidence. Chapter 51 details these occurrences, starting with Kakasaheb Dixit receiving a portrait of Baba from Madhavrao at the exact moment he longed for Baba's darshan. Later, when their train was too crowded, a guard who happened to be Dixit's acquaintance appeared to arrange first-class seats for them. Finally, upon reaching Kopergaon, they unexpectedly met Nana Saheb Chandorkar at the station, who was also on his way for Baba's darshan, leaving all three amazed by the unexpected coincidence.
