Based on Chapter 11, what methods did Sai Baba use to guide devotees from attachment to his physical form towards realizing the eternal, unmanifest reality?

Chapter 11 explains that Sai Baba employed various methods to help his devotees transition from attachment to his physical, Saguna form to an understanding of the eternal, Nirguna reality. According to the text, Baba would use countless means according to each devotee's eligibility. These methods could include sending a devotee to another country, confining them to solitude in Shirdi, or assigning them the task of reading scriptures. As Chapter 11 describes, practicing this for years would cultivate a deep longing for the Nirguna, where the devotee's mind would be constantly occupied with Baba's company, regardless of physical proximity. This was to teach them that the body is perishable, but the Unmanifest essence is eternal.
