Can you describe the miracle of Sai Baba's sleeping plank as mentioned in Chapter 10?

According to Chapter 10 of the Shri Sai Satcharitra, Sai Baba's sleeping arrangement was a marvel. He would sleep on a narrow wooden plank, merely four cubits long and one span wide, which was suspended from the rafters with old rags like a swing. The text highlights the miraculous nature of this, questioning how such a flimsy setup could support his weight. It explains that his movements of getting on and off the plank were imperceptible, meaning no one ever saw him do it. This feat is attributed to his Great Siddhis (powers), suggesting the plank was merely a prop. The chapter further elaborates that Baba possessed powers like 'Anima,' the ability to become minute, allowing his movements to be as subtle as those of insects or ants.
