How did Sai Baba manage to sleep on that tiny plank? Was it just a physical trick?

Chapter 10 explains that Sai Baba's ability to sleep on the narrow, suspended plank was not a physical feat but a display of his divine powers, or Siddhis. The text questions how such a plank, tied with mere rags, could support his weight, concluding that the plank was 'merely for name’s sake' due to the Great Siddhis residing within Him. Specifically, this chapter mentions the power of 'Anima,' which is the ability to become minute. It suggests that Baba could move with ease in the forms of flies, insects, or ants, which explains why his movements in getting on and off the plank were completely imperceptible to anyone.
