What were the extraordinary yogic practices, like Khanda-yoga, that Sai Baba performed as mentioned in Chapter 7?

Chapter 7 provides a glimpse into some of Sai Baba's extraordinary and seemingly miraculous practices. It specifically mentions his practice of Khanda-yoga, which is described as the disjointing of his own limbs. The text states that during this practice, his hands, feet, and head would be separated from his body and then joined back together as they were before. In addition to this, the chapter notes other experiments he undertook, such as Dhauti, which is a yogic cleansing of the stomach, and Poti. These practices are mentioned in the context of how Baba toiled for others and even bore the sufferings of his devotees upon his own body.
