What is the significance of receiving Udi from Sai Baba when one wishes to leave Shirdi?

According to the sacred texts, receiving Udi from Sai Baba is profoundly important as it serves as the official permission to depart from Shirdi. Chapter 35 explains that no one should leave by their own will, as transgressing Baba's command can invite dreadful interruptions and remorse. The established protocol involves bowing before Baba to ask for permission. The blessing, given along with the Udi Prasad, is the explicit sign that permission has been granted. As verse 156 states, 'The blessing along with the Udi is the permission to leave.' Therefore, the Udi is not just a sacred gift but a crucial part of the departure process, ensuring a safe and blessed journey home.
