Chapter 7 mentions some extraordinary yogic practices of Sai Baba. What were these, and what did they involve?

Chapter 7 describes Sai Baba's profound self-sacrifice and mastery over his physical body through extraordinary yogic practices. The text specifically mentions his practice of Khanda-yoga, which is described as the disjointing of his own limbs. In this state, his hands, feet, and head were sometimes separated from his body and then joined back together as before. This was done alongside experiments like Dhauti, a yogic cleansing of the stomach. These practices, as mentioned in Chapter 7, were part of how he toiled for the benefit of others and even bore the sufferings of his devotees, demonstrating his complete control over his physical form.
