Based on Chapter 46, how does Shri Sai interact with his followers, and what is the nature of his presence?

Chapter 46 of the Sai Satcharitra describes Shri Sai's interaction with his followers in a subtle and profound manner. It states that even though His physical form is invisible, His spirit in the Samadhi is awake, providing immediate experiences. He is depicted as holding a 'subtle string' with which He pulls His devotees towards Him, whether they are near or far. The chapter explains that He moves the strings of life in such a way that His presence is not obvious, yet devotees ultimately feel that He is standing right behind them, nourishing them with love like a mother does for her child.
