Describe the sequence of events that led to Dev's confusion, specifically explaining why he couldn't connect the Sanyasi to Sai Baba.

The confusion experienced by Dev stemmed from a specific sequence of events detailed in Chapter 40. First, a Sanyasi visited him to collect funds for cow protection, an event that happened before Dev even extended the Udyapan invitation to Sai Baba in Shirdi. Later, after Dev invited Baba, this same Sanyasi appeared for the meal. Because Dev's first interaction with the Sanyasi was about a worldly matter of fundraising, he mentally categorized him as such. When the Sanyasi returned for the meal, Dev's mind was clouded by this prior context, causing a 'delusion' that prevented him from seeing the Sanyasi as the divine manifestation of Sai Baba fulfilling his promise to attend the feast.
