According to Chapter 7, what specific yogic practices or miracles did Sai Baba perform that demonstrated his extraordinary capabilities?

Chapter 7 of the Shri Sai Satcharitra describes Sai Baba's remarkable and mysterious abilities, highlighting his practice of Khanda-yoga. This involved the apparent disjointing of his limbs, where his hands, feet, and head would be separated and then miraculously joined back together as before. The text also mentions his experiments with Dhauti, a yogic cleansing of the stomach, and how he would bear the sufferings of his devotees upon his own body. These practices are presented as evidence of his mastery over his physical form and his deep compassion for his followers.
