What was the significance of the portrait of Sai Baba that Kakasaheb Dixit received, and how did it come into his possession just before his trip to Shirdi?

The appearance of Sai Baba's portrait was a pivotal and joyous event for Kakasaheb Dixit. As recounted in Chapter 51, he was at Mirikar's house when Madhavrao was entrusted with a portrait of Baba. Madhavrao unveiled it and handed it to Dixit, saying, "Go happily to Shirdi in Baba's company." Dixit was overwhelmed with joy upon seeing the all-captivating image, as it was a darshan of the very Guru he longed to see. The timing was seen as a strange and wonderful coincidence, orchestrated by the capable Sai to fulfill Dixit's heartfelt desire, making it seem as if Baba Himself had come to meet him on the way.
