How does the chapter explain Baba's ability to sleep on a narrow plank suspended by rags? What specific powers are mentioned?

Chapter 10 explains that Sai Baba's ability to sleep on a narrow plank, just one span wide and hung by old rags, was a display of the great Siddhis (divine powers) he possessed. The text notes that the plank itself was 'merely for name’s sake,' implying the feat defied normal physics. It specifically mentions the power of 'Anima,' which is the yogic ability to become minute in form. This power allowed his movements to be as subtle and imperceptible as those of flies, insects, or ants, which explains why no one ever saw him get on or off the precarious plank.
