Why was Dev suspicious when the Sanyasi returned to Dahanu, and what did the Sanyasi ask for on his second visit?

Dev felt suspicious because the Sanyasi returned to Dahanu only about a month after their first meeting, much earlier than the two to four months Dev had suggested. As Chapter 40 recounts, Dev wondered to his son why the Sanyasi had come back so soon and if he had forgotten their previous conversation. However, on this second visit, the Sanyasi did not ask for money. Instead, he surprised Dev by stating, 'I haven't come for money; today we want a meal,' and mentioned he had two companions with him. Dev, despite his initial doubt, agreed to host them for a meal.
