According to Chapter 11, what specific methods did Sai Baba use to guide his devotees from attachment to his physical form towards the realization of the formless (Nirguna)?

To help his devotees progress from Saguna worship to the realization of the Nirguna, Sai Baba employed various unique methods tailored to their eligibility. Chapter 11 describes how Baba would create situations to foster a deeper, internal connection rather than a purely physical one. These methods included sending a devotee to another country, confining another to solitude in Shirdi, locking someone in the Wada, or assigning them the task of reading scriptures. As the text explains, by practicing these disciplines for years, the devotee's longing for the Nirguna would grow, and their mind would become constantly occupied with Baba’s company, transcending his physical presence.
