How does Chapter 46 portray Sai Baba's mysterious and all-pervasive nature?

Chapter 46 of the Sai Satcharitra beautifully illustrates Sai Baba's enigmatic nature. It states that even though His form may be invisible, His spirit residing in the Samadhi is awake and provides immediate experiences for devotees. He is described as holding a "subtle string," pulling His devotees towards Him from all over the world, much like a mother nourishes her child. The chapter highlights that while He moves the strings behind the scenes and plays all the games from within, He flies the flag of detachment and calls Himself a non-doer. This mysterious character is something no one can fully understand, leading to the conclusion that one should simply surrender at His feet.
