According to Chapter 11, what methods did Sai Baba use to guide his devotees from Saguna devotion to the realization of the Nirguna?

Chapter 11 of the Sai Satcharitra describes the countless means Baba employed to help his devotees transcend the physical form and realize the Nirguna, or unmanifest reality. According to this chapter, he would tailor his methods to the devotee's eligibility. 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. The purpose of these practices, which could go on for years, was to cultivate a deep longing and ensure the devotee's mind would be constantly occupied with Baba’s company, whether sitting, sleeping, or eating, ultimately leading them to focus on the eternal.
