Can you lay out the timeline that caused Dev to be so confused about the Sanyasi's identity during the Udyapan?

Dev's confusion stemmed from a specific sequence of events detailed in Chapter 40. The critical point is that the man in the Sanyasi's guise had first visited Dev for an entirely different reason—to collect funds for cow protection. This initial meeting happened before Dev extended the Udyapan invitation to Sai Baba in Shirdi. Therefore, when this same Sanyasi returned and was invited to the meal, Dev's mind categorized him based on their first encounter. He failed to connect this person with Baba's promise, even when the Sanyasi returned with two others as Baba had said he would. Dev himself later realized that this prior context created a "delusion" that prevented him from recognizing Baba.
