Who were the three uninvited guests at Dev's feast, and why was their presence so significant to the promise Sai Baba made?

The three uninvited guests who attended Dev's Udyapan ceremony were Sai Baba himself, disguised as a Sanyasi, and two unnamed companions he brought with him. Their presence was the direct fulfillment of Baba's promise. As recounted in Chapter 40, after Dev invited him, Baba had specifically stated he would come for the meal and bring 'two others with me.' Though they arrived unannounced and Dev failed to recognize them, their appearance and participation in the meal was Baba keeping his word to his devotee. The entire incident served as a powerful lesson that Baba's presence is not always obvious and that he always honors his commitments, even if his devotees fail to perceive it at the time.
