What extraordinary yogic abilities and practices of Sai Baba are mentioned in the seventh chapter?

The seventh chapter of the Shri Sai Satcharitra describes some of Sai Baba's remarkable and seemingly miraculous yogic practices. The text mentions his mastery of Khanda-yoga, a practice where he could disjoin the limbs of his body. It is stated that he would sometimes separate his hands, feet, and head from his torso and then rejoin them as they were before. In addition to this, Chapter 7 notes that he performed experiments like Dhauti, which is a yogic method for cleansing the stomach, and Poti. These accounts illustrate the extraordinary control he possessed over his physical body, which often left his devotees in awe.
