Can you describe the origin of the portrait Kakasaheb Dixit received and his specific reaction to seeing it for the first time?

The portrait of Sai Baba had been with Balasaheb, who entrusted it to Madhavrao before the end of a horse show. It was Madhavrao who then presented it to Kakasaheb Dixit. As per Chapter 51, Madhavrao moved the curtain covering the portrait and handed it over, saying, "Go happily to Shirdi in Baba's company." Upon seeing the image, Dixit's reaction was one of pure elation. Chapter 51 notes that when his eyes first fell on the "all-captivating portrait," he was "overwhelmed with joy" and looked at it with prostration. His eyes were said to be "transfixed," and he felt "extreme delight" that the very image he longed to see had appeared before him.
