What were the extraordinary physical yogic practices attributed to Sai Baba in this chapter?

Chapter 7 describes some of Sai Baba's extraordinary and miraculous physical abilities, highlighting his mastery over his body. The text mentions his practice of Khanda-yoga, which is described as the disjointing of his limbs. It states that sometimes his hands, feet, and head were separated and then joined back together as before. In addition to this, the chapter notes he performed experiments like Dhauti, which is a yogic cleansing of the stomach, and Poti. These practices are presented in Chapter 7 as examples of how he toiled for others' benefit and even bore the sufferings of his devotees upon his own body.
