What miraculous or yogic abilities of Sai Baba are described in Chapter 7?

Chapter 7 of the Shri Sai Satcharitra touches upon some of Sai Baba's extraordinary abilities. It specifically mentions his practice of Khanda-yoga, a process through which he could disjoint his own limbs. The text describes how his hands, feet, and head could be separated and then joined back together as before, often while in a state of Samadhi. In addition to this, the chapter makes a brief reference to other experiments like Dhauti, which is a yogic cleansing of the stomach, and Poti. These descriptions highlight Baba's complete mastery over his physical body for the benefit of others.
