Can you explain the significance of the portrait mentioned in the text? Why was receiving a photograph so important?

The portrait of Sai Baba holds immense significance in the story of Kakasaheb Dixit's journey. According to Chapter 51, Dixit was deeply longing for Baba's darshan. The sudden appearance of the 'all-captivating portrait' was seen as a direct response to this longing. The text notes that when his eyes first fell upon the photograph, 'Kakasaheb was overwhelmed with joy' and his 'eyes were transfixed.' It was considered a 'strange occurrence' and a sign that the capable Sai was acting to fulfill his devotee's wish. As Chapter 51 explains, receiving the portrait was a pivotal moment that solidified Dixit's attraction to Baba as a Guru, making the image a powerful medium for experiencing Baba's presence and grace.
