How does Chapter 10 explain Sai Baba's ability to sleep on a flimsy plank and move unnoticed?

Chapter 10 explains that Sai Baba's ability to sleep on a narrow plank suspended by rags was not a matter of ordinary physics but a demonstration of his divine powers, or Siddhis. The text poses the question of how such a plank could support his weight and concludes that with "Great Siddhis residing within Him, the plank was merely for name’s sake." It further elaborates on his powers by mentioning 'Anima,' the power to become minute. As Chapter 10 suggests, Baba could easily move in the forms of flies, insects, or ants, which explains why his movements of climbing up to and down from the plank were imperceptible.
