For a devotee preparing to depart from Shirdi, what was the significance of receiving Udi from Baba, based on Chapter 33?

As described in Chapter 33 of the Shri Sai Satcharita, receiving Udi from Sai Baba held a very practical and important significance for devotees leaving Shirdi. It was a well-known custom that when devotees asked for permission to return to their villages, Baba would give them Udi. The text clarifies that when Baba told someone to 'Take the Udi,' it was understood as the true granting of permission to depart. This act would fill the devotee with enthusiasm for their journey, serving as both a blessing and a tangible sign of Baba's consent and protection for their travels.
