Chapter 7 mentions some of Sai Baba's incredible yogic abilities. Could you describe them?

Chapter 7 of the Shri Sai Satcharitra describes some of Sai Baba's extraordinary yogic practices. It mentions His practice of Khanda-yoga, which is described as the disjointing of His limbs, where His hands, feet, and head would be separated and then joined back together as before. The text also refers to experiments like Dhauti, a yogic technique for cleansing the stomach, and Poti. These practices are presented as examples of how Baba toiled for the benefit of others and even bore the sufferings of His devotees, sometimes wearing out His own body in the process.
