According to Chapter 10, how was it possible for Sai Baba to sleep on a narrow plank tied with rags? Was it simply a physical feat?

According to the explanation in Chapter 10, Sai Baba's ability to sleep on the narrow plank was not a mere physical act but a demonstration of His divine powers, or Siddhis. The text questions how such a plank, tied with mere rags, could support His weight and concludes that the plank was "merely for name’s sake." It suggests that Baba possessed great Siddhis, including 'Anima,' the power to become minute. As Chapter 10 describes, this power allowed His movements to be as easy and imperceptible as those of flies, insects, or ants, explaining how he could ascend and descend without anyone ever knowing.
