Can you explain the yogic practices or miracles Sai Baba performed on his own body that are mentioned in Chapter 7?

Chapter 7 describes some of Sai Baba's extraordinary yogic abilities, highlighting how he would wear out his own body for the benefit of others. The text specifically mentions his practice of Khanda-yoga, a miraculous process where he could disjoint his limbs, separating his hands, feet, and head from his body, and then join them back together as they were before. In addition to this, the chapter notes his experiments with internal cleansing techniques like Dhauti, which involves cleansing the stomach, and Poti. These accounts from Chapter 7 serve to illustrate the incredible control Baba had over his physical form and his willingness to undergo suffering.
