How does Chapter 11 describe Sai Baba's relationship with the natural elements and his methods for guiding devotees toward realizing the formless (Nirguna)?

Chapter 11 highlights Sai Baba's complete authority over the five elements of nature, stating that deities like Indra, Agni, and Varuna obey his commands. This demonstrates his divine power. The chapter also details Baba's methods for helping devotees transition from devotion to his physical form (Saguna) to realizing the formless (Nirguna). He employed various means tailored to each devotee's eligibility, such as sending them to other places, confining them to solitude in Shirdi, locking them in the Wada, or assigning them the task of reading scriptures. These practices were designed to cultivate a deep longing for the Nirguna, so their minds would constantly be occupied with Baba's essence.
