How did Dev's perception of the Sanyasi's visit differ from the Sanyasi's initial purpose?

On the second visit, the Sanyasi's stated purpose was simply to have a meal. However, Chapter 40 explains that his 'previous purpose spread a veil of Maya,' influencing Dev's perception. Because of this, Dev's mind fixed on the idea that the visitor was simply 'some guest who has come to get a meal,' and this 'state of delusion strengthened.' He completely overlooked the Sanyasi's original intent to collect donations, seeing him only through the lens of a guest seeking food, thus simplifying the Sanyasi's complex motives for the visit.
