According to Chapter 46, how does Sai Baba continue to interact with his devotees even though his physical form is no longer visible?

Chapter 46 beautifully explains that even if Sai Baba's form is currently invisible, his spirit, residing in the Samadhi, is awake and provides immediate experiences for his followers. The text uses the metaphor of Baba holding a subtle string, by which he pulls his devotees towards him, regardless of whether they are in the country or abroad. He brings them to his feet and nourishes them with love, just as a mother nourishes her child. This illustrates that his presence is always felt, standing behind his devotees to guide and protect them.
