What are the key principles discussed in Chapter 9 of the Sai Satcharitra regarding devotees' travel to and from Shirdi?

Chapter 9 of the Sai Satcharitra emphasizes the critical importance of adhering to Sai Baba's permissions for travel. The chapter explains that leaving Shirdi without Baba's explicit consent often leads to obstacles and trouble for the devotee. Conversely, once permission to depart is granted, one should not delay, as staying longer also brings difficulties. The text provides examples, such as devotees being stranded without a carriage or even being looted by thieves, to illustrate the consequences of not following Baba's instructions. As detailed in Chapter 9, this rule was a well-known characteristic of the Shirdi pilgrimage, and many devotees experienced the repercussions of acting outside his orders.
