What specific superhuman abilities or miracles of Sai Baba are mentioned in the seventh chapter?

Chapter 7 describes some of Sai Baba's extraordinary abilities, highlighting his mastery over the physical body. It specifically mentions his practice of Khanda-yoga, a miraculous power where he could disjoint his own limbs—separating his hands, feet, and head from his body and then rejoining them as before. As detailed in Chapter 7, these practices, along with experiments like Dhauti (cleansing of the stomach), illustrate how Baba toiled for others and even bore the sufferings of his devotees, demonstrating his profound spiritual power and control over the physical form.
