How does the story of Dev's Udyapan ceremony illustrate the nature of Baba's promises and the concept of Maya?

The account of Dev's Udyapan ceremony in Chapter 40 serves as a profound lesson on Maya and the absolute reliability of Baba's word. When Baba promised to attend, Dev expected a specific, recognizable arrival. Instead, Baba came in the guise of an unknown Sanyasi. The narrative explains that a "veil of Maya" was spread, causing Dev to see only "some guest who has come to get a meal." This delusion was so potent that he remained doubtful even after personally serving them. Baba later affirmed the sanctity of his promise, stating, "for the sake of My word, I would die; but the words from My mouth shall never be otherwise." This demonstrates that while Baba's promises are always fulfilled, a devotee's perception, clouded by Maya and preconceived notions, can obscure this reality.
