Based on the source text, what is the relationship between a devotee's free will and Sai Baba's divine authority regarding travel to and from Shirdi?

The passages from Chapter 35 strongly suggest that a devotee's personal will is subordinate to Sai Baba's divine authority. The text poses rhetorical questions like, "Whose self-will would allow for Darshan or arrival in Shirdi?" It explicitly states that leaving by one's own will brings remorse, humiliation, and dreadful interruptions. This is contrasted with the proper way of departing, which requires receiving Baba's permission in the form of Udi. Therefore, while a person might feel they are making a choice, the narrative presented in Chapter 35 frames the entire process as being orchestrated by Sai, whose mercy is the true cause for a successful visit.
