How was the act of receiving Udi linked to a devotee's departure from Shirdi?

Chapter 33 highlights a specific protocol involving Udi for devotees leaving Shirdi. When devotees would ask for Baba's permission to return to their homes, the granting of this permission was symbolized by receiving Udi. The text explicitly states that when Baba said, "Take the Udi," it meant that true permission to leave was granted. This practice was known to all devotees and served to fill the departing devotee's mind with enthusiasm for their journey. Therefore, receiving Udi was not just a blessing but also a formal and cherished part of the process of leaving Shirdi.
