According to Chapter 9, what are the rules and consequences surrounding a devotee's departure from Shirdi?

As detailed in Chapter 9, there is a strict protocol for leaving Shirdi that devotees must follow. The text states it is a distinct characteristic of the Shirdi pilgrimage that departing without Sai Baba's permission invites obstacles and trouble. Some who acted outside his orders are said to have suffered greatly, even being looted by thieves. Conversely, the chapter also warns that once permission to leave is given, one should not stay in Shirdi for even a moment longer, as doing so also brings trouble. This demonstrates that Baba's timing is perfect and should be adhered to for the devotee's own safety and well-being.
