Analyze the reasons for Dev's 'delusion' and his failure to recognize Sai Baba in the form of the Sanyasi.

Chapter 40 provides a detailed account of Dev's self-analysis regarding his failure to recognize Baba. Dev's 'delusion' stemmed from a confluence of factors. Firstly, the timing of the Sanyasi's initial appearance was crucial; he came to collect funds for cow protection before Dev had even formally invited Baba to the meal, leading Dev to see him as just a fundraiser. Secondly, Dev admitted his own oversight: "Only one word of Baba's—'When I come for the meal, two others will come with me'—I forgot to pay attention to that." He was so fixated on the idea of Baba physically traveling from Shirdi that his vision became, in his own words, "confused." This sequence of events and his preconceived expectations created a "veil of Maya" that prevented him from recognizing his Guru.
