The text mentions Baba's movements were 'imperceptible.' How does Chapter 10 explain his ability to move unseen, particularly in relation to his sleeping plank?

Chapter 10 explains that Sai Baba's movements were often imperceptible, a quality demonstrated by His mysterious use of a suspended sleeping plank. While He would sit or sleep on this narrow plank, tied with rags, no one ever witnessed how He got up or down. The chapter attributes this to the Great Siddhis (powers) residing within Him. Specifically, it references the power of 'Anima,' which is the ability to become minute. As Chapter 10 suggests, the Master of 'Anima' can hide easily, and Baba’s movements were effortless in the forms of flies, insects, or ants, explaining how He could move about completely unseen by His devotees.
