How did a portrait of Sai Baba play a pivotal role in initiating Kakasaheb Dixit's journey to Shirdi?

The portrait of Sai Baba was the key catalyst for Kakasaheb Dixit's pilgrimage. According to Chapter 51, while Dixit was at Kakasaheb Mirikar's house, a portrait of Baba, which had come from Shirdi and remained covered, was suddenly unveiled for him by Madhavrao. The text describes this as a "strange occurrence." The moment Dixit's eyes fell upon the "all-captivating portrait," he was overwhelmed with joy and prostrated before it. This event was seen as a direct response from Sai to Dixit's longing for darshan, making him feel that the very image of the one he longed for appeared right on his path. This seemingly coincidental event solidified his resolve and set him on the path to Shirdi with Madhavrao, carrying the very same portrait with them.
