How did Sai Baba's promise to visit Dev unfold, and what was Dev's ultimate reaction to the event?

Sai Baba's promise to visit Dev unfolded in an enigmatic way, not as a direct appearance but seemingly through the arrival of three uninvited guests: a Sanyasi and his two companions. As described in Chapter 40, Dev had invited Baba to his Udyapan ceremony. The Sanyasi's arrival and request for a meal for three people corresponded with the promise, but Dev was unable to recognize this as the fulfillment. His ultimate reaction was one of profound disappointment and confusion. He felt that Baba's word had failed or that he had been deceived, as he did not have the clear, unambiguous experience he had anticipated. This led him to write a letter to his friend Jog, expressing his frustration and seeking an explanation for why he was left feeling so let down.
