What extraordinary yogic practices of Sai Baba are described in Chapter 7?

Chapter 7 mentions several of Sai Baba's remarkable abilities and practices. It highlights his practice of Khanda-yoga, a miraculous feat where he could disjoint his limbs—separating hands, feet, and head—and then join them back together as before. The text also notes his experiments with yogic cleansing techniques like Dhauti, which involves cleansing the stomach. These accounts illustrate how he toiled for others and even bore the sufferings of his devotees, sometimes wearing out his own body in the process, as explained in this chapter.
