Based on Chapter 46, how does Sai Baba interact with His devotees even after his physical form is no longer visible?

Chapter 46 explains that even though Sai Baba's form is currently invisible, his spirit, described as a light residing in the Samadhi, remains awake and active for his devotees. The chapter emphasizes that for those who hold faith and devotion, he provides immediate experiences. He is depicted as having a subtle string with which he pulls his devotees towards him, whether they are in the same country or abroad. He then holds them to his chest with love and nourishes them effortlessly, much like a mother nourishes her own child, demonstrating a continuous and loving connection beyond physical presence.
