How did the act of receiving Udi from Sai Baba signify permission for a devotee to leave Shirdi?

Chapter 33 clarifies a specific and well-known custom regarding departure from Shirdi. When devotees wished to return to their homes and sought Baba's permission, the act of him giving them Udi was the definitive signal of his consent. The text explicitly states that when Baba uttered the words "Take the Udi," it meant that true permission was granted. This gesture would make the devotee feel enthusiastic about their journey, as it was understood by all that receiving the Udi was Baba's blessing and formal approval to depart.
