Based on Chapter 46, how does Sai Baba interact with his devotees even after his Mahasamadhi?

Chapter 46 of the Sai Satcharitra explains that even though Sai Baba's physical form is invisible, his presence is profoundly felt. The text states that the light or spirit residing in his Samadhi is awake and provides immediate experiences for devotees who maintain faith and devotion. It describes Baba as holding a 'subtle string' with which he pulls his devotees towards him, regardless of their location. Just as a mother lovingly nourishes her child, Baba holds his devotees to his chest, making them feel that he is standing right behind them, guiding and protecting them.
