How does Chapter 10 describe Sai Baba's ability to transcend ordinary physical laws and perception?

According to Chapter 10, Sai Baba's movements were often imperceptible, especially concerning how he got onto his suspended sleeping plank. The text explains that this was possible due to the Great Siddhis (powers) residing within him. It posits that for the Master of 'Anima,' the power to become minute, movements were easy. He could potentially move in the forms of flies, insects, or ants, rendering his actions invisible to the human eye. The chapter suggests that the plank, seemingly too flimsy to support his weight, was merely a prop to demonstrate these divine capabilities.
