According to Chapter 35, what is the specific connection between receiving Udi and a devotee's departure from Shirdi?

Chapter 35 establishes a direct and crucial connection between receiving Udi and being permitted to leave Shirdi. The text emphasizes that no one can arrive at or depart from Shirdi without Sai Baba's will. The formal process for departure involves asking for permission, and as the scripture states, 'The blessing along with the Udi is the permission to leave.' Receiving this Udi Prasad is not just a parting gift but a necessary sanction from Baba. The chapter warns that leaving by one's own volition, without this specific blessing, is considered a transgression that invites remorse, humiliation, and 'dreadful interruptions' on the journey. Therefore, the Udi symbolizes Baba's grace and consent, ensuring a safe and blessed departure for the devotee.
