According to Chapter 11, what specific methods did Sai Baba employ to guide his devotees toward spiritual realization?

Chapter 11 details the various methods Sai Baba used to help his devotees realize the Nirguna, or formless aspect of the divine, tailored to their individual spiritual eligibility. As described in the chapter, Baba would use countless means for this purpose. For instance, he might send one devotee to another country, confine another to solitude within Shirdi, lock someone in the Wada (lodging), or assign them the specific task of reading scriptures. The text suggests that by practicing these disciplines over many years, the devotee's longing for the Nirguna would intensify, and their mind would become constantly occupied with Baba’s divine company.
