Can you explain the story behind the portrait of Sai Baba mentioned in the text and why it took nine years for the full story to be told?

Chapter 41 recounts a fascinating incident involving a portrait of Sai Baba. The narrator had made a firm decision with a priest named Ismu that this powerful image should be presented to a specific person. The narrator successfully delivered the portrait, but because the recipient was about to have a meal, there was no opportune moment to share the long history behind it. The narrator intended to explain everything at a later, more leisurely time. However, as life unfolded, a full nine years passed before the narrator and the recipient had an unexpected meeting, prompted by the recipient's sharing of a wonderful dream. It was only then that the original story was finally remembered and recounted.
