How does Chapter 46 describe Sai Baba's connection with His devotees, especially after he is no longer physically visible?

Chapter 46 of the Sai Satcharitra explains that even though Sai Baba's physical form is invisible, the spirit or light residing in his Samadhi remains awake and provides immediate experiences for devotees with faith. The text uses the metaphor of a 'subtle string' that Baba uses to pull His devotees towards Him, whether they are in the country or abroad. As described in this chapter, He brings them to His feet and nourishes them with love, just as a mother nourishes her child. Furthermore, it states that wherever a devotee goes, Sai reaches there beforehand, often giving unexpected visions, and resides near them twenty-four hours a day.
