Analyze the role of 'Maya' or delusion in Dev's failure to recognize Sai Baba during the Udyapan ceremony.

The story in Chapter 40 provides a deep analysis of how 'Maya' can obscure a devotee's perception. The text explicitly mentions that a 'veil of Maya' was spread by the Sanyasi's 'previous purpose.' Dev himself later identified the source of his delusion: the Sanyasi had first appeared to collect funds for cow protection *before* the Udyapan invitation was sent. This prior context fixed a worldly identity onto the Sanyasi in Dev's mind. Dev admitted his 'pride of knowledge' and reasoned that if the Sanyasi had appeared only after the invitation, his 'vision would not have been so confused.' This demonstrates how preconceived notions and logical reasoning can prevent one from recognizing the divine, even when it manifests exactly as promised.
