Can you explain the misunderstanding that led Dev to believe Sai Baba had broken his promise to attend the Udyapan ceremony? What was Dev's reasoning for not recognizing Baba?

The misunderstanding arose from a combination of Dev's expectations and a prior encounter. As detailed in chapter 40, Dev was expecting a more obvious or miraculous appearance from Sai Baba. When a Sanyasi and two companions arrived uninvited, Dev simply saw them as ordinary guests and his "veil of Maya" was strengthened. His failure to recognize Baba was further cemented by a previous meeting. The same Sanyasi had visited Dev before the Udyapan invitation was even sent to Baba, seeking funds for cow protection. Because this first visit was for a worldly purpose, Dev did not connect the returning Sanyasi with Baba's subsequent promise to attend the meal, leading to his confusion and disappointment.
