According to Chapter 33, what was the significance of receiving Udi from Baba when a devotee wanted to leave Shirdi?

As narrated in Chapter 33 of the Shri Sai Satcharitra, receiving Udi from Sai Baba held a special significance for devotees who wished to return to their homes. The text clarifies that when devotees asked for permission to leave Shirdi, Baba's practice was to give them Udi. The act of Baba saying 'Take the Udi' was considered the true granting of permission to depart. This gesture would fill the devotee's mind with enthusiasm for their journey home, as it was a clear and positive signal of Baba's blessings and consent for their departure. This was a well-known custom among all devotees.
