How did receiving Udi signify permission for devotees to leave Shirdi, and what was Baba's general policy on giving it?

As detailed in Chapter 33, the practice of giving Udi was deeply integrated into the lives of devotees in Shirdi. It was a common and known practice that when devotees asked for Sai Baba's permission to leave Shirdi and return to their villages, he would give them Udi. This chapter states that when Baba said, "Take the Udi," it was understood that true permission had been granted, and the devotee could depart with enthusiasm. Beyond this specific circumstance, Baba's general policy was one of constant generosity. He would not send anyone away empty-handed, distributing Udi in the mornings, afternoons, and evenings to those who came to him.
