How did Sai Baba manage to attend Damodar Dev's Udyapan ceremony even though he physically stayed in Shirdi?

Sai Baba attended Damodar Dev's Udyapan ceremony by appearing in the guise of a Sanyasi. According to the account in Chapter 40, after Dev complained that Baba had not kept his promise, Baba explained the situation to Jog. He revealed that while his physical body never left Shirdi, he went to the ceremony as a holy man, first appearing alone and then returning for the meal with two other companions, just as he had promised. Baba confirmed, "I said I would come with two others, and I went with two others." The narrative describes how this Sanyasi and his companions were served a full meal and treated with respect by Dev, who remained entirely unaware that his revered guest was Sai Baba himself.
