Why was Damodar Dev so disappointed and confused after his Udyapan ceremony?

Damodar Dev was deeply disappointed and confused after his Udyapan ceremony because he believed Sai Baba had broken his promise to attend. As detailed in Chapter 40, Dev had lovingly invited Baba, who had assured him, "I am coming." Dev waited with great anticipation but failed to recognize Baba when he appeared in the guise of a Sanyasi. Feeling let down, he wrote a letter to Jog, expressing his sorrow and confusion by asking, "How is it that Baba deceived me?" This sense of being forgotten by his Guru, despite having hosted uninvited guests, left him feeling doubtful and dejected, as he couldn't comprehend why his heartfelt invitation seemingly went unanswered.
