According to Chapter 46, how does Sai Baba interact with his followers now that his physical form is no longer visible?

Chapter 46 of the Sai Satcharitra explains that even though Sai Baba's physical form is invisible, his spirit or 'light' residing in the Samadhi is perpetually awake. This allows him to provide immediate experiences for his devotees. The text describes this as a 'subtle string' with which he pulls his followers towards him, regardless of whether they are in the same country or abroad. He brings them to his feet and nourishes them with love, much like a mother cares for her child, demonstrating that his presence and protection continue beyond his physical existence.
