Can you explain the story of how Sai Baba attended Dev's Udyapan ceremony even though he physically remained in Shirdi?

This story illustrates Baba's ability to be in multiple places at once. As described in Chapter 40, a devotee named Dev was holding an Udyapan ceremony and invited Baba, who promised to attend with two others. Dev was disappointed when Baba didn't seem to arrive. However, a Sanyasi had appeared earlier and then returned at noon with two companions. They were fed and left. Later, Baba confirmed through Jog that he had indeed been the Sanyasi. He said, "I said I would come with two others, and I went with two others... for the sake of My word, I would die." This revealed that Baba had kept his promise in a mysterious way, strengthening Dev's faith after an initial period of doubt and dejection.
