According to Chapter 11, what specific methods did Sai Baba use to guide devotees from worshipping his physical form to understanding the formless, eternal reality?

Chapter 11 of the Sai Satcharitra details the practical methods Sai Baba employed to help his devotees transcend from Saguna (manifest) worship to Nirguna (unmanifest) realization. The text states that Baba used countless means tailored to each devotee's eligibility. These included sending a devotee to another country, confining someone to solitude in Shirdi, locking a person in the Wada, or assigning them the task of reading scriptures. According to the chapter, practicing these disciplines over many years was intended to cultivate a deep and constant longing for the Nirguna, ensuring their minds were always occupied with Baba's eternal essence.
