How does the text explain Dev's inability to recognize Sai Baba in the form of the Sanyasi?

The text attributes Mamlatdar Dev's inability to recognize Sai Baba to a spiritual illusion or a "veil of Maya." Chapter 40 explains that when the Sanyasi came for a meal with two others, "his previous purpose spread a veil of Maya." This illusion clouded Dev's perception, causing him to see only "some guest who has come to get a meal" rather than the divine presence he had invited. The narrative emphasizes this point by stating, "Even though they came uninvited and ate at that time, it did not occur to Dev that it was Baba; the doubt remained in the mind." This suggests that Dev's expectation of a straightforward appearance, combined with the Sanyasi's prior mundane request for money, created a mental block that prevented him from seeing the truth of the event.
