How does Chapter 10 describe Baba's ability to be imperceptible and his relationship with his Siddhis, or powers?

Chapter 10 highlights Baba's imperceptible movements, particularly regarding the narrow wooden plank he slept on. No one could ever witness him climbing up or down from it. The text questions how such a flimsy plank tied with rags could support his weight, concluding that the plank was merely for show, given the great Siddhis (powers) residing within him. It further explains that the Master of 'Anima', the power to become minute, could easily hide in a tiny particle, suggesting that Baba could move about in the forms of flies, insects, or ants, making his movements undetectable.
