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

Chapter 7 describes some of Sai Baba's profound yogic abilities. It mentions his practice of Khanda-yoga, which is explicitly defined as the 'disjointing of limbs.' The text elaborates on this with experiments like Dhauti (cleansing of the stomach) and Poti, during which his hands, feet, and head were sometimes separated and then joined back together as before. This chapter also notes his capacity to bear the sufferings of his devotees upon his own body, showcasing his deep compassion and control over his physical form.
