I've heard that Sai Baba had power over nature. Does Chapter 11 mention anything about his control over the elements?

Yes, Chapter 11 of the Sai Satcharitra explicitly introduces the theme of Sai Baba's authority over the forces of nature. The text states that the chapter will demonstrate Baba's greatness by illustrating how the deities who preside over the elements, specifically Indra (rain/sky), Agni (fire), and Varuna (water), obey his commands. While these specific source chunks set the stage rather than narrating a full story, they make it clear that his control over the five elements is a key aspect of his divine plays, or 'leelas,' as described in Chapter 11. This mastery is presented as a testament to his supreme power.
