What specific miracles or extraordinary yogic practices of Sai Baba are mentioned in the seventh chapter?

Chapter 7 of the Shri Sai Satcharitra details some of Sai Baba's extraordinary yogic practices. It describes His practice of Khanda-yoga, which involved the disjointing of His limbs, separating His hands, feet, and head from His body, and then rejoining them as before. The text also mentions other experiments like Dhauti, which is a cleansing of the stomach, and Poti. These practices highlight His supernatural abilities and control over His own physical form, demonstrating how He would even bear the sufferings of His devotees through such means, as recounted in this chapter.
