What does Chapter 10 reveal about Sai Baba's Siddhis, particularly in relation to his sleeping plank?

Chapter 10 explains that Sai Baba's ability to sleep on a narrow plank suspended by mere rags was a display of His great Siddhis, or divine powers. The text questions how such a flimsy setup could support His weight, concluding that the plank was 'merely for name’s sake' and was actually sustained by His powers. The chapter specifically mentions the Master of 'Anima,' the power to become minute, suggesting Baba could easily move in the forms of flies, insects, or ants. This power is given as the reason why His movements in climbing up to and descending from the plank were always imperceptible to onlookers.
