According to Chapter 11, what specific methods did Sai Baba use to help his devotees progress from devotion to his physical form towards an understanding of the eternal, formless reality?

Chapter 11 describes several methods Sai Baba employed to guide devotees toward realizing the formless (Nirguna). As the chapter details, Baba used countless means according to a devotee's eligibility. These included sending a person to another country, confining someone to solitude in Shirdi, locking a devotee in the Wada lodging, or assigning them the task of reading scriptures. The purpose of these practices, which could last for years, was to make the devotee's mind become constantly occupied with Baba's company, thereby fostering a longing for the eternal, unmanifest reality beyond the perishable physical body.
