What was the significance of Sai Baba's portrait in Kakasaheb Dixit's spiritual journey, and how did it come into his possession on the way to Shirdi?

The portrait of Sai Baba played a pivotal role in initiating Kakasaheb Dixit's journey to Shirdi. According to the narrative in Chapter 51, this 'all-captivating portrait' had been brought from Shirdi and was entrusted to Madhavrao. It remained covered at Kakasaheb Mirikar’s house until the perfect moment. When Madhavrao unveiled it in front of Dixit, who already longed for Baba's darshan, the effect was immediate and profound. Dixit was overwhelmed with joy and his eyes were transfixed on the holy photograph. He saw this as a strange and wonderful coincidence, feeling that Baba's very image had appeared on his path to fulfill his heart's desire, acting as the catalyst for his immediate departure to Shirdi.
