Based on Chapter 10, how did Sai Baba's divine powers, or Siddhis, manifest in his daily life, particularly in his sleeping habits?

Chapter 10 explains that Sai Baba's ability to sleep on a narrow plank suspended by rags was a demonstration of his divine powers, or Siddhis. The text explicitly states that with "Great Siddhis (powers) residing within Him, the plank was merely for name’s sake." The physical support was an illusion; his power sustained him. The chapter further elaborates on his abilities by mentioning his mastery of 'Anima,' the power to become minute. It suggests that Baba's movements could be as subtle and easy as those of flies, insects, or ants, which is why no one ever witnessed him getting on or off the plank. This illustrates that his daily actions were imbued with a divine power that transcended the understanding and perception of ordinary people.
