Based on Chapter 11, what specific techniques did Sai Baba employ to help his followers transition from Saguna worship to realizing the Nirguna?

According to Chapter 11, Sai Baba used countless and often unusual methods to help his devotees realize the Nirguna, or formless reality, based on their individual eligibility. The chapter provides specific examples of these techniques. He might send one devotee to another country, confine another to solitude within Shirdi, lock a person in the Wada (lodging), or assign them the task of reading scriptures for long periods. As the text explains, by practicing these disciplines for years, the devotee's mind would become constantly occupied with Baba's company, fostering a deep longing for the Nirguna, the beginningless and endless Eternal.
