Chapter 33 mentions Baba's practice of giving Udi. What was the connection between receiving Udi and a devotee's permission to leave Shirdi?

Chapter 33 of the Shri Sai Satcharita clarifies the specific role Udi played in granting devotees permission to depart from Shirdi. It was a well-known practice among all devotees that when they wished to return to their villages, they would seek Baba's permission. The chapter explicitly states that when Baba said, "Take the Udi," it signified that true permission was granted. This act of receiving the Udi would fill the devotee's mind with enthusiasm for their journey home. This was part of Baba's daily practice, which also included giving Udi to those staying in Shirdi at various times of the day, but its function as a farewell blessing and formal permission was a distinct and important aspect of the tradition described in this chapter.
