Chapter 10 mentions Baba's movements were 'imperceptible.' What examples are given to illustrate this, and what does it suggest about his nature?

Chapter 10 illustrates Baba's imperceptible movements primarily through the example of his sleeping plank. Despite sleeping on a narrow plank suspended by rags, no one ever knew when he got up or down. The chapter posits that this was possible due to the Great Siddhis (powers) residing within him. It specifically suggests that the Master of 'Anima' (the power to become minute) could easily hide in plain sight, and that Baba's movements were easy in the forms of flies, insects, or ants. This suggests his divine nature, capable of transcending the physical limitations and perceptions of ordinary humans.
