Describe the specific interactions between Dev and the Sanyasi who was actually Baba at the Udyapan.

The Sanyasi, who was Baba in disguise, first appeared alone before the ceremony, causing Dev to initially worry he was there to ask for money. However, the Sanyasi clarified he would return only for the meal with two others. As detailed in chapter 40, he returned at noon with two companions, and Dev served them all a satisfying meal. Dev treated them as honored guests, completing all the rituals such as offering water, mouth fresheners, sandalwood paste, and perfume. Despite serving these three uninvited guests in person, Dev's mind was clouded by delusion, and he failed to recognize the Sanyasi as Baba, thinking of him only as a guest who had come for a meal.
