Chapter 10 mentions that Baba's movements were 'imperceptible'. How does the text elaborate on this, especially regarding his sleeping habits?

Chapter 10 emphasizes the mysterious nature of Baba's movements by focusing on his use of a narrow wooden plank suspended from the ceiling. The text explicitly states that when he climbed up to this plank or descended from it, his movements were "imperceptible" and that "no one ever knew" how he did it. This wasn't just about being quiet; it was a supernatural quality. The chapter explains this phenomenon by linking it to his divine powers (Siddhis), specifically mentioning the power of 'Anima' (the ability to become minute). It suggests that Baba could move as easily and unnoticeably as insects, making his physical presence and actions beyond the comprehension of ordinary observers.
