Can you explain the Siddhis or divine powers of Sai Baba that are mentioned in Chapter 10?

Chapter 10 specifically discusses Sai Baba's Great Siddhis (powers) in the context of his mysterious ability to sleep on a narrow, suspended plank. The text posits that the plank was 'merely for name’s sake' because his powers made the physical impossibilities irrelevant. It explicitly mentions the Master of 'Anima', which is the yogic power to become as minute as an atom. The chapter suggests that through such powers, Baba's movements could be as subtle and easy as those of flies, insects, or ants, explaining why no one could ever perceive Him getting on or off the plank. This demonstrates that his actions were not bound by ordinary physical laws.
