How does Chapter 35 explain the connection between receiving Sai's Darshan, his divine will, and the gift of Udi?

Chapter 35 intricately connects Darshan, divine will, and the Udi. It establishes that no one could come for Darshan or even arrive in Shirdi unless Sai himself willed it, quoting Baba's saying, "No one comes unless I bring them." This depended on mercy arising in his heart. Similarly, departure was also not a matter of personal choice. The text explains that unless Sai's heart is pleased, no one gets permission to leave. This permission was physically manifested through the gift of Udi. After a devotee bowed to ask for leave, receiving the Udi Prasad was the ultimate confirmation of Sai's consent, making the sacred ash a pivotal symbol of his divine will governing a devotee's entire pilgrimage.
