Based on the provided text, how does the story of Madhavrao and Dixit's journey demonstrate Sai Baba's active intervention in his devotees' lives?

Chapter 51 illustrates Sai Baba's active intervention through a chain of seemingly orchestrated events. The narrative posits that the 'capable Sai acted to fulfill' the desires of his devotees. This is shown when Baba's portrait materializes for Dixit right when he is longing for darshan. The text explicitly suggests this was not a coincidence, but a pretext for Baba to make his presence felt. Later, a logistical crisis occurs when their train is full. Just as they decide to turn back, a solution arrives in the form of an acquaintance who provides first-class seats. The chapter culminates in the 'unexpected coincidence' of meeting Nana Saheb Chandorkar at the destination, reinforcing the theme that Baba was clearing obstacles and arranging favorable encounters for them.
