Chapter 10 mentions Baba's movements were imperceptible. What explanation does the text offer for this and his ability to rest on such a narrow, suspended plank?

The text in Chapter 10 attributes Sai Baba's seemingly impossible feats to his Great Siddhis, or divine powers. It questions how a simple plank tied with rags could support his weight, concluding that the plank was "merely for name’s sake" and that his powers were the true support. For his imperceptible movements, the chapter suggests he possessed powers like 'Anima,' which is the ability to become minute. It posits that Baba could move with ease in the forms of flies, insects, or ants, which is why no one ever saw him ascend or descend from his sleeping plank.
