What is the central message of Chapter 46 regarding Sai Baba's presence and his connection with devotees?

Chapter 46 conveys that even though Sai Baba's physical form is no longer visible, his spirit residing in the Samadhi is awake and provides immediate experiences for his devotees. The chapter beautifully describes this connection as a subtle string with which Baba pulls his devotees towards him, whether they are near or far. As stated in Chapter 46, he brings them to his feet and nourishes them with love, just as a mother nourishes her child. This illustrates his continuous, loving presence and active role in the lives of those who hold faith and devotion.
